How does the exchange of gases occur in roots of a​

Answer 1

Answer:

In plants, gas exchange occurs through small pores in the leaf surface called stomata. Stomata can open to allow the exchange of gasses and close to reduce water loss from the plant. In the covering of the secondary structure of the stem of woody plants gas exchange is made through the lenticels of the periderm (small breaches of the cork). The cork of mature roots is also perforated by non-suberized pores called lenticels. These enable oxygen to reach the intercellular spaces of the interior tissues and carbon dioxide to be released into the atmosphere.

Answer 2

Answer:

The exchange of gases also occurs in the roots of plants. ... This oxygen enters the root hairs through diffusion and then it reaches other cells of roots for respiration. Carbon dioxide produced during respiration move outside through the root hairs in the same way by the process of diffusion.
