HORTICULTURE

Detailed explanation-1: -A waxy cuticle covers all aerial surfaces of land plants to minimize water loss.

Detailed explanation-2: -Water loss through transpiration can be reduced by closing the stomata in the leaves using a substance called ABA. When the stomata is closed photosynthesis will decrease because no CO2 can enter through the closed stomata.

Detailed explanation-3: -To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.
