What are the small holes on the surface of the paper? The answer is required, one option
The answer is: stomata
On the surface of the leaf are small openings called stomata, surrounded by guard cells.
The stomata play an important role in the exchange of gases between the leaf and the surrounding atmosphere, as they allow carbon dioxide to enter the leaf and oxygen to escape from it.
Stomata are one of the main reasons plants respire and grow, and keep them healthy.
Therefore, the surface of the leaf must be kept clean and free from obstacles that prevent the transmission of gases, in order to ensure the necessary food and oxygen for plants.
