What are stomata? Give two functions of stomata.

Stomata are small pores in plant leaves that help in breathing and releasing water vapor. They play two vital roles: first, by taking in carbon dioxide (CO2) for plants to make food through photosynthesis, and second, by releasing oxygen (O2) into the air. Stomata also control the amount of water a plant loses, which is important for keeping the plant hydrated and healthy.
