How Are Broad Leaves And Needle Leaves Different?

How are broad leaves and needle leaves different? Broad-leaved trees live in areas where the soil is nutritious enough to produce a new set of large, sun-collecting leaves every spring. Needle-leaf trees, or conifers, have long, thin leaves that resemble needles.

Why do some leaves have broad leaf blade and others have needle shaped leaf blade?

The trees growing in hilly areas have needle-shaped leaf blades because it rains heavily in these regions and the needle-shaped leaves help the rainwater and snow to slide off easily. So, plants that grow near the ground have broad leaf blades to capture as much sunlight as possible.

Why do plants have broad thin leaves?

The leaves are broad to maximize surface area for light harvest and they are thin since light cannot penetrate too deeply into the leaf (the amount of light decreases exponentially with distance).

Do broadleaf trees have needles?

When conditions are favorable, broad leaves are more efficient than the needles and scales of conifers. Larches rely on needles rather than broad leaves and they grow new needles every year (although the needles of juvenile trees may survive the first winter—perhaps protected by the forest canopy above).

What type of plants have needle like leaves?

Conifers have leaves that resemble needles and generally remain on a tree year-round. They are replaced slowly and continuously.

Which plants have needle shaped leaves?

Pines, spruces, firs and cedars are some trees with needle shaped leaves. The leaves have needle shape because of dryness in air to prevent the water loss due to transpiration.

Why is the blade of the leaf broad?

The main light-collecting structure on a leaf is a large, broad, flat surface called the leaf blade. The blade has many layers that not only help the plant move but also help it store materials and byproducts of photosynthesis. The blade is held away from the stem and sup- ported by the petiole.

How do leaves differ and similar to each other?

Explanation: The leaves are different for different plants. They are different from the leaves of other by shape ,texture, margins base,tips, veins, forms and types,and several other characters by which they are identified.

Why do trees in the taiga have needle shaped leaves?

Needles on evergreen trees of the taiga are thin and wax-covered. Needles are adapted to the taiga environment. Needles lose less water and shed snow more easily than broad leaves.

What is a broad leaf plant?

A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones.

What is the advantage for a plant to produce broad leaves compared to narrow needle-like leaves?

What is the advantage for a plant to produce broad leaves compared to narrow needle-like leaves? Broad leaves provide more surface area for water loss.

How are needle like leaves adaptations?

The needle-like leaves are an important adaptation to Conifer trees because they do not accumulate much snow, keeping the weight load mild. The waxy cuticle on the epidermis is an extremely important adaptation because it protects the photosynthetic cells that are below in the mesophyll.

What is a needle leaf?

: populated with trees having leaves that are needles needleleaf evergreen forests also : having leaves that are needles needleleaf trees.

Why do mountain plants have needle shaped leaves?

The trees growing in hilly areas have needle-shaped leaf blades because it rains heavily in these regions and the needle-shaped leaves help the rainwater and snow to slide off easily. So, plants that grow near the ground have broad leaf blades to capture as much sunlight as possible.

Which trees have needle-like leaves and bear cones?

cedar. pine.

What is needle shaped?

Definitions of needle-shaped. adjective. narrow and long and pointed; as pine leaves. synonyms: acerate, acerose, acicular simple, unsubdivided. (botany) of leaf shapes; of leaves having no divisions or subdivisions.

Why do leaves have different shape?

Why do tree leaves have different shapes? The shape of a tree's leaves are a response to the tree species' long term ecological and evolutionary histories. A leaf must take in carbon dioxide from the surrounding air via pores (called "stomatae"). This carbon dioxide is also needed for photosynthesis.

Why are some leaves spiky?

Dr Dana Royer, who authored the study with Dr Peter Wilf at Pennsylvania State University, says that the jagged, pointy edges on leaves are packed with xylem, a tissue that transports water and nutrients in sap. Most of the liquid evaporates by leaving the teeth through minuscule pores.

What is the broad green part of the leaf called?

Solution: The green, flat and broad portion of the leaf is called lamina or leaf blade.

Why do plants have hairs?

Plants use hair for some of the same reasons animals do: to keep them warm, cool, or protected. Plants also use hair to collect food or distribute seeds. Insect-eating pitcher plants even have down-turned hairs to keep insects from escaping.

How does the shape of a leaf fit its function?

The leaves are the organ for photosynthesis. Most leaves are broad and so have a large surface area allowing them to absorb more light. A thin shape. A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.

What makes plants different from each other?

Each plant species has its own characteristics. The plants vary in many ways. The plants vary by the number of leaves they might have in a group, shape of the leaves, what color the flowers are or when the flowers might bloom. Botanists use these differences or characteristics to help identify the plants.

How do plant leaves vary?

The number and placement of a plant's leaves will vary depending on the species, with each species exhibiting a characteristic leaf arrangement. Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral.

What determines leaf shape?

Genetic basis of leaf shape: genetic interactions, gene expression patterns, microRNAs, and active hormonal regulations.

Why do trees have broad leaves in cold forest?

Broader leaves provide much higher surface area to trap the incident light for photosynthesis than leaves of taller treesand hence , productivity and rate of photosynthesis are more in trees having broader leaves

Which of these trees have leaves that are waxy and needle like?

Coniferous trees have small, waxy and usually narrow leaves (needles or flat scales). 'Coniferous' means that it is a cone-bearing tree. The most common conifers are spruces, pines and firs.

Which trees have broad leaves?

A spotter's guide to broad-leaved trees

  • Hazel. The long, drooping catkins of the hazel are one of the earliest signs of spring, appearing in January or February.
  • Oak. The oak is our most important native broad-leaved tree, providing a home for hundreds of species of insects.
  • Beech.
  • Sycamore.
  • Horse chestnut.
  • Ash.

  • How do you identify a broad leaf?

    Identification: Characteristics of Broadleaf Plants

    Broadleaf plants have relatively broad leaves, whereas leaves of grasses and sedges are bladelike. Leaves of broadleaves have one main vein from which smaller veins branch.

    Why do deciduous trees have broad leaves?

    Broad, leathery leaves grow in clusters at the tips of shoots. Their shape makes them very good at capturing the Sun's rays so that they can make food (photosynthesis).

    What are the advantages of having a broad and flat leaves?

    Leaves that are broad and flat are better equipped for photosynthesis. They have more surface area through which they can absorb sunlight.

    Why does some plants have big leaves?

    The extra insulation makes it harder for the leaf to extract heat from the surroundings at night. But large leaves can cope in hot, wet, tropical climates because they counteract the daytime heat-trapping effect using transpiration – something desert plants cannot do because they cannot afford to lose that much water.
