NEET BIOLOGY

Detailed explanation-1: -To save water in desert plants, transpiration takes place at night and rate of transpiration is low when compared to water and forest plants. Option B is correct. Was this answer helpful?

Detailed explanation-2: -The lower the humidity the easier it is for the plant to release water. The type of plant is also a factor in how much a plant will transpire. For example plants grow in arid hot areas such as the desert will transpire less as they aim to conserve water.

Detailed explanation-3: -But more than simply having low rainfall, a desert is “arid”. This means a high rate of water loss through plant reclamation (called transpiration) and through evaporation.

Detailed explanation-4: -In desert plants, epidermis has a thick waxy coating of cutin (chemical substance with waterproof quality) on its outer surface helps them to reduce the rate of water loss.

Detailed explanation-5: -In order to survive in these extremely dry climates, desert plants have evolved adaptations to reduce transpiration while maintaining photosynthesis. Transpiration occurs when water vapor leaves the plant through openings on leaves called stomata, or singular stoma.
