Question

name the respiratory organs in
(1) young green stems
(2) Woody stems​

Answer 1

Answer:

1. Respiration In Stems. In the plants having herbaceous stem exchange of gases takes place through stomata and the carbon dioxide produced during the process gets diffused into the air via stomata only.

2. In woody stems, there is a special organ called lenticels which helps in the respiratory exchange of gases. Lenticels are the tissue which consists of large intercellular spaces in the periderms layer. The tissues are porous in nature and functions as a pore which helps in direct exchange of gases in the woody stems.
