Question

23. How do the roots of land plants get oxygen for respiration ?​

Answer 1

Plants respire through the tiny pores on the surface of their leaves called stomata . ... The roots of plants also respire. They do so by taking in oxygen from the air spaces present in soil. This oxygen enters the root hairs through diffusion and then it reaches other cells of roots for respiration.

Answer 2

Answer:

The roots of a plant take up air from the spaces between the soil particles. Root hairs are in contact with the air in the soil particles. 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.
