Question

Explain three modification of leaves.

Accepted Answer

Leaves of many plants, which have to perform specialised functions, undergoes changes or become modified into distinct forms.

Leaf tendrils: In some plants, leaves are modified into slender, often closely coiled structures known as tendrils. Tendrils are climbing organs and are sensitive to contact with a foreign body. Therefore, whenever they come in contact with a neighbouring object, they coil around it and help the plant to climb. Examples are pea plant, glory lily and wild pea.

Leaf spines: Leaves of certain plants become wholly or partially modified into sharp, pointed structures known as spines. These spines can be used for defensive purposes or may also be a means to check the rate of transpiration. Prickly pear or cactus is an example of this modification.

Scale leaves: These are typically thin, dry, stalkless, and membranous structures, usually brownish or sometimes colourless. Their function is to protect the young leaf bud that they bear in their tips. When scale leaves are thick and fleshy, as in onion, then their function is to store water and food. Onion is an example of plants with scale leaves.
