LIFE SCIENCE

Detailed explanation-1: -Adaptation in aquatic plants has a waxy coating on the leaves in which chlorophyll is only confined to the green on the top surface. There are no roots and hair from the root so there is no need to consume water; they have air pockets on leaves to absorb oxygen from water.

Detailed explanation-2: -To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved. The stomata can open and close depending on weather conditions. When it’s hot and dry, the stomata close to keep water inside of the plant.

Detailed explanation-3: -Cuticle – It is an epidermal layer seen in vascular plants, cells of this layer release cutin which is a waxy substance, preventing water loss from the stomata.

Detailed explanation-4: -The root system is smaller and holds the plant. Stems are long, hollow, light and grow up to the surface of the water. Leaves are mostly thin and ribbon-like. Tissues usually have air spaces to keep the plants afloat. More items
