Describe the process of respiration in the following parts of a plant :
(a) Root
(b) Stem
(c) Leaves

(a) The root hair present on the root helps in respiration by diffusion. The oxygen present in between the soil particles is taken in and carbon dioxide produced by the cells moves out through these root hair by the process of diffusion.
(b) The stems of the herbaceous plants contain stomata that help in the exchange of gases and carbon dioxide present in the air diffuses out through the same pores. Lenticels present in the woody stems also helps in the exchange of gases.
(c) ​The respiration in leaves takes place through the tiny pores called stomata present on them. The exchange of gases occurs through these pores. The oxygen is transported to other cells of the plant and carbon dioxide is removed from the cells by diffusion.
