Examples of plants that have narrow leaves

There are different types of plants based on their habitat, region of growth and climate adaptations. They can further be classified based on other factors like their life span, physical appearance, reproduction, presence of flowers, food requirement, etc. But taxonomical classification of plant relies on specific features which run through a set of plants. This botanical classification is more precise to read for academics but for knowledge purposes we can see them more differently.

Plants are the longest living creatures on the earth. Some of them live for even to years are more. But not all plants live the same age. Some of them even die within months.

So plants are differentiated based on their live span as. Ephemerals :. These are the plants with short life span.

They live for only few weeks. They germinate, grow, reproduce and die within few weeks. These are present even in deserts. These plants survive for a year or less. Most of the agriculture crop plants come under this category. Biennial plants : These plants survive for two years at most. Ex: Carrot. Perennial plants.

These plants grow for many years.Desert vegetation often appears different than plants that grow in other types of environment or biomes. Desert plants grow in one of the harshest environments on Earth, and therefore benefit from special adaptations that help them to survive.

These adaptation enable desert plants not only survive, but to thrive in hot and dry desert conditions. Such adaptations of desert plants are described below. Some plants avoid dry conditions by completing their life cycle before desert conditions intensify. These plants usually mature in a single season and then die, but produce seeds that later blossom into new plants. In some cases, not all seeds germinate at the same time, but remain dormant and germinate the following year or even years later.

Plants that germinate in the fall grow slowly through the winter and flower in the spring, after which they die before the scathing summer begins.

The plant life cycle continues through the seeds produced. Since desert plants are usually rare and have sparse populations, it is important for them to protect themselves against animals or other predators.

As such, these plants have several adaptations that prevent animals from approaching them. Hunger and thirst draw animals to plants, but many desert plants have spines and thorns, such as the barrel cactus, that can harm an animal that attempts to eat it. Many of these plants are also toxic, such as the desert thorn-apple, and some are both spiny and toxic.

Certain plants also use camouflage as a means to avoid being eaten by animals, such as the Arizona night-blooming cereus.

Plants usually absorb carbon dioxide during the day through stomata in their leaves to perform photosynthesis. However, openings of the stomata also lead to the loss of valuable water through evapotranspiration.

Desert plants cannot afford to lose water, and therefore some plants perform Crassulacean acid metabolism CAM photosynthesis for carbon fixation. In CAM photosynthesis, stomata remain closed during the day but open at night to absorb carbon dioxide, which is then stored in the vacuoles as malate.

During the day, malate is transported to chloroplasts, where its reconversion to carbon dioxide allows the remaining steps of photosynthesis to occur.

Yuccas, xerophytic bromeliads, and epiphytic orchids are examples of plant species that perform CAM photosynthesis. Desert plants have smaller leaves, seasonal leaves or no leaves at all. Species with small leaves, such as the little leaf palo verde tree or Parkinsonia microphylla, have less surface area on leaves and therefore lose less water through evapotranspiration. Plants like acacia and ocotillo, which are summer deciduous, drop their leaves during the hot season. As soon as weather conditions improve, these plants re-foliate.Basically, leaves are categorized into simple and compound forms.

This article will provide you with information about compound leaf identification. We all know that in most of the plants and trees, leaves are responsible for carrying out photosynthesis.

It is this process that helps the plants to make their food. Apart from that, leaves can also store food and water. In some plants, leaves are modified for these purposes. There are thousands of different plants and trees in the world and most of them have leaves of different, shapes, sizes and colors.

Distinguishing the leaf types is one of the key factors that will help in identifying specific trees. So, it is a common fact that leaves may not be similar for all plants and trees. They may have different shapes, sizes, patterns and arrangements. A leaf has a lamina or leaf blade, which is the main broad part of the leaf, which is attached to the petiole, which in turn joins the stem. The location where the petiole joins the stem is called the leaf axil, which sports two small bud-like structures called stipules.

This is only a generic description of a typical leaf, but some leaves may not be broad, whereas some may not have petioles or stipules. Basically, leaves are classified into simple and compound types. As the names rightly suggest, simple leaves are those leaves in which the leaf blade or lamina is undivided. For example, the leaf of a hibiscus plant has a leaf blade with no lobes or division. Most of the pear plants, basil, oregano and rubber plant are found to have simple leaves.

However, some of the simple leaves have lobes the leaf blade will be dividedbut the gaps between the lobes do not reach the mid vein of the leaf. For example, a sassafras tree leaf has three lobes, but is a single leaf as shown in the first image below. In such cases, the division of the leaf blade creates three lobes, but not three leaflets. Other examples for such simple leaves with lobes include most of the maples, sycamore, black oak and scarlet oak.

The following images are that of some simple leaves. Now you know that the leaf blade of a simple leaf is undivided. But, some of the simple leaves have partial division of leaf blades, forming lobes and not distinct leaflets. If you find a leaf with complete division of leaf blade, then it is a compound leaf. One such example is rose plant.

In this case, the leaf is divided completely along the mid vein, to form leaflets. Each of these leaflets may appear like a simple leaf. The stem on which the leaflets are arranged is called a rachis modified middle vein. There are different types of compound leaves, which are categorized into different forms.

A simple form is trifoliate or trifoliolate type. It can be inferred from the name that these compound leaves have three leaflets only. For example, leaves of common beans, strawberry, soy beans, white clover and laburnum, are found to have trifoliate leaves. A leaf in which the leaflets are arranged in pairs, along the mid vein or rachis is called a pinnately compound leaf.

If there is no terminal leaflet, then it is even pinnate mahogany, candle bush and tamarind and if there is a terminal leaflet, then it is an odd pinnate leaf like some acacia, mockernut hickory, pecans and roses. In some plants like flame trees otherwise known as royal poinciana or flamboyantbird of paradise tree and silk trees Albiziayou may find a rachis, along which compound leaves are arranged.Diverse marine, aquatic and terrestrial plants evolved long before dinosaurs roamed the Earth.

From their humble beginnings as single-celled algae, plants have evolved clever adaptations to survive and reproduce even in the harshest environments. You can find fascinating examples of plant adaptions when comparing vegetation in desert, tropical rainforest and tundra biomes. Biomes are areas of similar climate and temperature that have distinctive plants and animals that have adapted to the conditions of the region. Similar biomes can be found in discontinuous geographical areas.

Biomes around the world are divided into broad categories such as the desert, tundra and rainforest biome. Plants contain genetic material in the nucleus of their cells that is passed down through generations. In any plant population, there will be random mutations during gamete cell division, as well as variations in behavior, physiology and other special features that give certain organisms an evolutionary edge.

Charles Darwin posited that this process leads to the evolution of structural adaptations in a population that improve fitness and viability. For example, behavioral adaptations include going dormant during unbearable heat or equally difficult conditions and returning later. Similarly, desert plants with narrow leaves are more fit for retaining water in the desert than plants with broad leaves that have a wide surface area. Over time, plants that survive and reproduce become the dominant species via natural selection.

Nonvascular plants with simple structures such as mosses and liverworts were the first plants to adapt to a terrestrial environment. Ferns evolved next, followed by seed-bearing gymnosperms such as conifers and ginkgoes. Flowering angiosperms including hardwood trees, grasses and shrubs evolved the ability to make seeds enclosed in protective ovules.

Plant life proliferated after plants developed the ability to produce seeds that traveled long distances in the wind. Gymnosperms were soon outnumbered by angiosperms that gained the evolutionary upper hand.

The fruit of angiosperms provides extra nutrition and protection for the seeds. Today, flowering plants are ubiquitous around the world. Angiosperm pollen is smaller than male gymnosperm pollen, so it can reach eggs faster. Some types of seeds survive digestion when animals eat and excrete the seeds, which further aids their wide distribution and proliferation.

Deserts are arid lands that stay parched for long stretches of time. Without adaptations, plants would wither and die. Temperatures rise and fall to extremes, and some regions receive as little as 10 inches of annual rainfall. Seeds may be dormant for years before there is enough moisture to sprout.

What Is A Weed: Weed Info And Control Methods In Gardens

Desert plants look very different from plants found in other biomes due to the methods that they have adapted to obtain water, store water and prevent water loss. Such specific adaptive strategies have evolved to help desert plants cope with conditions inhospitable to most living organisms.

Evening Primrose has a long, thick taproot that helps this plant reach and store water and nutrients. Like some cacti, the primrose plant becomes active at night, and flowers bloom when temperatures are cooler. Pinyon pines have vertical and horizontal root systems that reach out 40 feet in both directions to provide water.

Extensive root systems help the tree grow and produce edible pine nuts in resin coated cones that prevent water loss. Juniper are gymnosperms with sharp, pointed needles or waxy scales adapted for less water loss. Long tap roots help these trees and shrubs reach deep into the bedrock for water. A slow growth rate expends less energy and helps preserve water.Weeds are an all too common occurrence in lawns and gardens.

While some may be deemed useful or attractive, most types of weeds are considered a nuisance. Learning more about weed info and control can make it easier for gardeners to decide whether these weeds should be welcomed or if they must go.

So what are weeds and where do weeds grow? Weeds are competitive, fighting your garden plants or lawn grass for water, light, nutrients and space. Most are quick growers and will take over many of the areas in which you find them. While most types of weeds thrive in favorable conditions, native types may be found growing nearly anywhere the ground has been disturbed.

In fact, they may even offer clues to your current soil conditions. There are generally three types of common weed plants in regards to their growing characteristics. These include:.

In addition to their growing type, common weed plants may belong to one of two families: broadleaf Dicot or narrow leaf Monocot.

Broadleaf types have larger leaves and grow from tap roots or fibrous root systems, whereas narrow leaf or grasses have long narrow leaves and fibrous roots systems. There are a number of weed control methods, depending on the weed and the gardener. Here are your options:.

These include: Annual types β€” Annual weeds germinate and spread by seed, having an average lifespan of one year. These include both winter and summer types. Summer annuals, such as lambsquartersgerminate in spring, grow throughout summer and are gone with the arrival of cold weather. Biennial types β€” Biennial weeds complete their life cycle in two years, germinating and forming rosettes their first year and producing flowers and seeds their second year.

Examples of these types include: bull thistle and garlic mustard. Perennial types β€” Perennial weeds return every year and normally produce long tap roots in addition to seeds. These weeds, which include dandelionsplantainand purple loosestrifeare the most difficult to control.CopyrightNational Gardening Association.

Though there are many variations, most leaves are composed of a thin sheet-like blade attached to the stem with a leaf stalk, or petiole PEH-tee-ole; La. At the base of the petiole where it attaches to the stem is the axillary bud. On some plants the axillary bud is covered by a structure called the stipule.

Adaptations in Leaves that Desert Plants Have

The diagrams below represent a typical simple leaf and compound leaf. Leaf Parts Simple leaf. Leaf Parts Compound Leaf. Different plants' leaves vary in: their ability to shed or conserve water how much surface area they expose to sunlight how much sunlight they allow to pass through to lower leaves weight--and how strong a petiole they require how much battering by wind and rain they can tolerate before they disintegrate. Climate, location, and competition from other plants all affect a leaf's ability to do its job--capture light.

For example, plants growing in shaded environments often have relatively large leaves to maximize the surface area exposed to the limited sunlight. On the other hand, the grasses in open prairies get plenty of sunlight, but they must contend with winds that can blow plants over and break their stems. A grass plant's tall, narrow leaves are less likely to be torn by the wind than are broad, sail-like leaves.

Of course there are no hard-and-fast rules, and there are plenty of small-leaved, shade-loving plants! Looking at Leaves.

For example, plants with thick, fleshy leaves or waxy coatings are often native to arid climates where these characteristics help them conserve water. These plants should be watered sparingly, because overwatering can quickly lead to root rot.Your help is appreciated. We depend on donations to help keep this site free and up to date for you. Can you please help us? Key Characteristics What we think of as the "daisy" flower actually is a composite head containing one or two kinds of flowers: ray flowers with flat, often strap-shaped corollas and disk flowers tubular flowers with 5 tooth-like lobes at the summit.

Important characteristics of the flower head include color, shape flat-topped or roundedthe leaf-like bracts that enclose the base of the head, and shape of the seed-like fruit cypsela. If you don't have flowers, note whether the plant has milky sap or an odor. Also see if the stem is rounded or has edges. Note how leaves are arranged, if they're simple or compound, and if they have hairs or spines. Exceptions The Aster family includes daisies and sunflowers, but also species with less showy flowers like thoroughwort, joe-pye weed, wild lettuce, and goldenrod.

It's easiest to see the flower characteristics with a hand lens or microscope. View a video about this subgroup. Key Characteristics This very diverse group is generally not woody, grass-like, or aquatic, and does not have composite flower heads. These plants have alternate leaves that join the stem at different levels, not opposite each other or in whorls; be sure to look at the arrangement of leaves in the lower half of the flowering stem.

Exceptions Leaf arrangement can vary from the bottom to top of the stem, or in young vs. Some crowded leaves may look opposite or whorled, but look closely to see whether there is actually space between them on the stem.

Some species have narrow leaves where it's hard to see the veins, so look for other features such as petal number, presence of leaf teeth, etc. Key Characteristics These species are herbaceous plants with only all basal, opposite, or whorled leaves; they are not aquatic, grass-like, and do not have composite flower heads.

Some species are parasitic or lack green leaves. Some species such as teasel or pincushions have flower heads that look like those of the aster family, but look closely: the flowers usually have four tooth-like lobes a rare condition in the aster family and the fruit is partially enclosed in a tubular bract.
