Read the following statements
(I) Many xerophytic plants have thick cuticle on leaf epidermis and sunken stomata.
(II) Some xerophytic plants have special photosynthetic pathway (CAM) that enables their stomata close during day.
(III) Opuntia has spines (modified leaves), photosynthetic stems.
(IV) Adaptations are genetically fixed in organisms.

Many adaptions have evolved over a long evolutionary time & are genetically fixed. Many desert plants have a thick cuticle on their leaf surfaces and have their stomata arranged in deep pits (sunken) to minimize water loss through transpiration. They also have a special photosynthetic pathway (CAM) that enables, their stomata to remain closed during day time. Some desert
plants like Opuntia, have no leaves - they are reduced to spines-and the photosynthetic function is taken over by the flattened stems.
