NEET - Medical UG-2015 Medium

Answer & Solution:

Solution: Opuntia

Opuntia, commonly called prickly pear, is a genus in the cactus family, Cactaceae.

Leaves get modified to perform some special functions other than the normal ones, such as photosynthesis and transpiration, in some plants. Sometimes these modifications are in response to certain environmental conditions. Leaves of certain plants become wholly or partially modified for defensive purpose into sharp, pointed structures known as spines. In Opuntia this modification is brought about to reduce loss of water through transpiration in dry environmental conditions.
