Question

(a) Plants lack a specialised respiratory system. How do they carry out respiratory process? Explain.
(b) The plant roots being underground respire by using which mechanism?

Answer 1

Answer:

1. Roots, stems, and leaves of plants exchange gases for respiration separately. As we all know, leaves have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by cells in the leaves to break down glucose into carbon dioxide and water.
2. Oxygen from the air in soil particles diffuse into root hair and reach all the cells of the root where it is utilised in respiration. Carbon dioxide produced in the cells of the root during respiration goes out through the same root hair by the process of diffusion.
