75. Give reason for

(c) Leaves of submerged aquatic plants contain wax coating.

Answer 1

Leaves of submerged aquatic plants contain wax coating because-

• Aquatic plants spend the majority of their time immersed in water, their leaves are wide in order to capture more sunlight.
• The waxy coating present on leaves of hydrophytes prevents wetting and clogging of stomata ​and extra water intake.
• As a result, they developed a waxy coating on their leaves to limit sap loss owing to osmosis.
• Therefore, leaves of submerged aquatic plants contain wax coating.
