Detailed explanation-1: -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.

Detailed explanation-2: -This is the vascular tissue. Xylem tissue carries water absorbed by the plant’s roots up into the leaf. Phloem tissue carries the food made during photosynthesis throughout the plant.

Detailed explanation-3: -Case: Transpiration is the evaporative loss of water by plants. It occurs mainly through the stomata in the leaves. Besides the loss of water vapour in transpiration, exchange of oxygen and carbon dioxide in the leaf also occurs through pores called stomata.
