Vector diagram for educational, biological and science use This was a brief introduction of the Diagram of Stomata. 1 answer. vii. In floating leaves Stomata are confined only on the upper surface of the leaf. However, most plants do not have the aforementioned facility and must therefore open and close their stomata during the daytime, in response to changing conditions, such as light intensity, humidity, and carbon dioxide concentration. Epidermal cells are irregularly shaped cells, which functions by providing mechanical support to the plant. Stomata are open during the day because this is when photosynthesis typically occurs. The mesophyll cells store the acids at night during the day and light reactions supply ATP and NADPH for the calvin Cycle 21. Vector. 25.
