Question

The gaseous wastes of respiration and photosynthesis in plants are removed through :

• A. Stomata of leaves
• B. Lenticels of stem
• C. Stomata and lenticels
• D. None of these

Answer 1

The correct option is C

Stomata and lenticels

The gaseous wastes of respiration and photosynthesis in plants are removed through stomata and lenticels.Lenticels are a body of cells on the stem which acts as a pore and enables the transfer of gaseous wastes into the atmosphere while Stoma is a pore found in the epidermis of leaves and stems and controls the gaseous exachange in plants. The exchange of gases through these pores is by simple diffusion.
