Stomata of Too much oxygen in the leaf leads to a process called photorespiration, which is when the enzymes involved in photosynthesis wastefully bind to oxygen instead of carbon dioxide. This can be harmful to humans as well as other life forms. You also have the option to opt-out of these cookies. Stomata remain open during the day and close at night in most plants. Guard cells usually keep stomata open during the day and closed at night because during the night there is no sunlight for photosynthesis. Under these conditions, rapid stomatal closure (i.e., hours after first being exposed to cold stress) limits water loss. In the night time, a plant cannot carry out photosynthesis, hence they only respire (take in oxygen). Plants cannot photosynthesize during the night and therefore they need no carbon dioxide influx. Due to this the water potential in the guard cells decreases and water moves inside the guard cells causing them to swell up and become turgid which in turn causes the opening of stomata pores. . Plants make their food through photosynthesis which require sun light water and chlorophyll. Under drought, plants may also close their stomata to limit the amount of water that evaporates from their leaves. Stomata look like tiny mouths which open and close as they assist in transpiration.
