Question

how does the exchange of gases occur roots of a plant
(1)Through lenticels (2)Through root stomata(3)Through root hairs(4)None of these​​

Answer 1

Answer:

The exchange of gases through the stomatal pore is dependent upon the turgidity of the guard cells. Stomata are mainly present on the surface of the leaves apart from the epidermal surface of young stem. ... In roots stomatal pores as well as lenticels are absent, exchange of gases occurs through root hairs.

Answer 2

Answer:

1. In leaves respiration takes place by diffusion of oxygen through stomata into the cells of the leaf from where the carbon dioxide is released into the atmosphere.

2. The exchange of gases in roots of a plant takes place by the process of diffusion. During diffusion, oxygen diffuses into the root hairs and passes into the root cells, from where the carbon dioxide moves out into the soil.
