Question

How does respiration occur in the roots of the plants?

Answer 1

In the plants having hard and woody stems and mature roots the exchange of gases takes place through lenticels. Lenticels are actually loosely packed dead cells which are present as small pores on the bark of woody plants or old roots. These enable oxygen to reach the intercellular spaces of the interior tissues and carbon dioxide to be released to the atmosphere by the process of diffusion.
