Q.12:- How do the various leaf modifications help plants?
Modification of Leaves
Tendrils: In some plants, leaves are modified into tendrils to assist in climbing, e.g. pea.
Spines: In some plants, leaves are modified into spines for defence, e.g. cactus. The leaf spine in cacti and in some other xerophytes also helps in reducing water loss by preventing transpiration.
Bulb: In some plants, the leaves are modified into bulb for food storage, e.g. garlic and onion.
