Question

Explain the process of conduction of gases in plants.​

Answer 1

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.

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.

Answer 2

Xylem and phloem tissues are involved in the conduction processes within plants. Sugars are conducted throughout the plant in the phloem, water and other nutrients through the xylem. Conduction occurs from a source to a sink for each separate nutrient.
