Question

Name the process by which plant parts like roots, stems and leaves get the oxygen required for respiration.

Answer 1

1. Respiration is the biochemical process involving the complete breakdown of food particles inside the cells to obtain a large amount of energy.
2. The name of the process by which plant parts like roots, stems and leaves get the oxygen required for respiration is diffusion.
3. Diffusion is defined as the process of movement of molecules through a semipermeable membrane from a region of higher concentration to a region of lower concentration.
4. Root hairs of the root exchange the respiratory gases with the air of soil through diffusion.
5. In stems of woody plants, respiration occurs through lenticels.
6. The exchange of gases in the stomata of the leaf takes place by a process of diffusion.
