Question

Aquatic plants excrete metabolic wastes through

• A. Transpiration
• B. Shedding of leaves
• C. Diffusion
• D. All of the above

Answer 1

The correct option is C Diffusion

Aquatic plants respire and dispose of wastes by diffusion. Diffusion is a process by which oxygen and nutrients dissolve in water and reach aquatic plants. The waste materials diffuse out of the plants as diffusion takes place from higher concentration to lower concentration. Shedding of leaves occurs in deciduous trees. The process of getting rid of excess water in form of water vapour is called transpiration.

So, the correct answer is 'Diffusion'.
