Question

List five adaptations found in desert plants to reduce transpiration.

Accepted Answer

Desert plants have evolved various adaptations to reduce transpiration and conserve water in their arid environments. Five common adaptations are:

Thick Cuticle: Desert plants like the banyan tree develop a thick waxy cuticle over the epidermis to minimize water loss by transpiration.

Sunken Stomata: Some desert plants, like Nerium, have sunken stomata, often covered with hairs, creating pockets with still air to reduce water loss.

Palisade Parenchyma: Many desert plants replace spongy parenchyma with palisade parenchyma in their leaves, enhancing water conservation.

Reduced Stomata: These plants have a reduced number of stomata, typically concentrated on the underside of leaves to shield them from direct sunlight.

Nocturnal Stomata Opening: Succulent plants from the Crassulaceae family open their stomata only at night when the air is cooler and more humid, storing carbon dioxide for daytime photosynthesis while keeping stomata closed to prevent water loss.
