Discuss two adaptation inplants that help to reduce transpiration

Plants exhibit some adaptations to reduce the rate of transpiration, these are as follows-

•  Thick cuticle cover − The waxy layer of cuticle over the epidermis prevents excessive transpiration.
•  Number of stomata − The number of stomata in leaves is reduced and they are usually concentrated on the lower side of the leaf in order to reduce the water loss.
• Sunken stomata − In some leaves, the stomata sink into the leaf and get covered by hair. 
• Epidermal hair − The leaf surface is sometimes covered by a thick coating of hair to reduce transpiration
