Respiration in Plants
Plants like other animals also respire. Plants also need energy. The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy.
This energy is used by the plant for carrying out its various life processes. Thus, Like other organisms, plants also respire for their survival. The respiration in plants differs from that of animals. In other words, in plants, each part can independently take in oxygen from air, utilize it to obtain energy, and give out carbon dioxide.
The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata.
This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.
