Question

Which one of the following is not an excretory product in plants?

• A. \(CO_2\)
• B. Starch
• C. Resins and gums
• D. Dead cells

Hint:

Excretory products in plants include gases like \(CO_2\), resins, gums, and dead cells.

Answer 1

The Correct Option is B

Plant excretory products are metabolic byproducts that offer no benefit to the plant.
- \(CO_2\) is a waste product of cellular respiration. - Plants secrete resins and gums for defense.
- Non-functional dead cells are also waste.
Starch, which stores energy, is not an excretory product. Therefore, the correct choice is (B) Starch.
