Question 10

Unlike animals, plants do not have any excretory products as they do not eat food. Comment upon the statement with justification.

Answer:
The statement is incorrect.

• Plants also carry out metabolic activities like photosynthesis and respiration which produce waste products.

• Gaseous wastes like oxygen (from photosynthesis) and carbon dioxide (from respiration) are removed through stomata and lenticles.

• Some wastes are stored in leaves, bark, and fruits which later fall off.

• Other wastes like gums, resins, latex, and oils are stored in special cells and ducts.

👉 Thus, plants too have excretory products, but their method of excretion is different from animals.
