At night, the stomata close to avoid losing water when photosynthesis is not occurring. During the day, stomata close if the leaves experience a lack of water, such as during a drought. The opening or closing of stomata occur in response to signals from the external environment.
specialized cells known as guard cell surround stomata and function to open close stomata pores. stomata allows to take in carbon dioxide which is needed photosynthesis they also help to reduce water loss byclosing when conditions hot or dry
