What is the modification of leaf?

What is the modification of leaf?

A modification of the leaf is phyllode. Let’s begin with different modifications of leaves. The whole leaf or part of it is often modified for performing special functions such as climbing and substrate attachment, protection against predation or climatic conditions, storage or trapping and digesting insect prey.

What are the different functions of leaves?

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

How do the various leaf modifications help plants?

The main function of the leaves is to carry out the process of photosynthesis. However, in a few plants, leaves are modified to perform different functions. (a) Tendrils: The leaves of a pea plant are modified into tendrils that help the plant in climbing. The petioles in these plants synthesize food.

Why are leaves sometimes modified give two examples of leaf modifications?

Answer: In many plants, leaves get modified to perform some special functions other than the normal ones, such as photosynthesis and transpiration. Some plants of xerophytic habitats and members of the family Crassulaceae generally have highly thickened and succulent leaves with water storage tissue.

Which organ is modification of Phyllode?

Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether.

Why do leaves of some plants get modified?

Leaf spines to provide protection and reduce the loss of water: In certain plants, leaves or parts of leaves get modified into pointed structures called spines. Spines help to reduce the loss of water by transpiration. They also protect the plant from grazing animals.

What is the role of spines The modified leaves?

Spines are also modified leaves. In cacti, spines are wholly transformed leaves that protect the plant from herbivores, radiate heat from the stem during the day, and collect and drip condensed water vapour during the cooler night.

What is the example of modified fleshy leaves?

Leaves of the flowering plants are mainly involved in the process of photosynthesis. However, the leaves of the onion plant become fleshy and swollen to store water and food substances. The onion bulb represents the reduced disc-shaped stem while its fleshy scales are the leaf bases.

How are the leaves of a plant modified?

The leaves are modified into slender wiry and. coiled structures called leaf tendrils and support climbers to climb. Pisum Sativum. 2) Spines. The leaves modified into a pointed structure and usually protect them from herbivores. Opuntia. 3) Phyllode. It is a green extended structure formed by the modification of petiole or rachis

What are the functions of leaves in plants?

In many plants, leaves get modified to perform some special functions other than the normal ones, such as photosynthesis and transpiration. Sometimes these modifications are in response to certain environmental conditions. 1. Storage Leaves:

What are the functions of leaf modification in carnivorous plants?

Leaf modifications can also enhance the way a carnivorous plant traps insects. Leaf modifications can result in enhancing the plant to be more attractive, trapping and digesting. Shaping the leaves help the plant become more successful in eating it’s insects.

What are the functions of leaf modification in barberry?

The leaf-apex in date-palm, dagger plant (Yucca) etc., is so modified, while in plants like prickly or Mexican poppy (Argemone), American aloe (Agave), Indian aloe (Aloe), etc., spines develop on the margin as well as at the apex. In barberry, the leaf itself becomes modified into a spine; while the leaves of the axillary bud are normal.
