Answer:
- guard cells

- Carbon dioxide
Explanation:
Stomata are pores in the leaf surface of plants. they regulate the exchange of moisture and gases in plants. They open at night for the exchange absorption of Carbon dioxide and expulsion of Oxygen, while closing at the middle of the day to prevent evaporation of moisture or water in transpiration. These pores are opened or closed depending on the state of the two surrounding guard cells.
The somata are found on both the upper and the lower leaf surface. in dicots, the stomata are noticeably denser on the lower leaf surface, while they are evenly distributed on both leaf surfaces on monocots.
