Answer: They take in carbon dioxide and release carbon oxygen.
Explanation:
Stomata are small pores present over the surface of the leaves and on some stems. They are responsible for the exchange of gases from the internal environment of the leaves to the external environment. They allow the entry of carbon dioxide from the atmosphere and release out oxygen during the process of photosynthesis.
Answer - They take in C02 (Carbon Dioxide) & Release O2 (Oxygen)
Reasoning - To be able to do Photosynthesis they Plants need C02 which is one of the important components to making Glucose. During that gas exchange they release O2 for C02.
