Question

Roots, stems and leaves of plants exchange gases for respiration separately.

• A. True
• B. False

Answer 1

The correct option is A True

Leaves of plants have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by the cells in the leaves to break down glucose into carbon dioxide and water. Similarly, roots of plants take in air from the air spaces present between the soil particles. Thus, the oxygen absorbed through roots are used to release energy. In the case of the stem, the air gets diffused in the stomata and passes through various parts of the cell for respiration.
