Answer: Stomata are the spots on posterior surface of the leaflets of fern.
- Stomata are tiny openings or pores that enable gaseous exchange. They are usually found in plant leaves, but they can also be found in some stems.
- Apart from water vapour loss in transpiration, exchange of oxygen and carbon dioxide in the leaf also occurs through these stomata.
