Answer» . Astomais the opening on a plant leaf, but there are specialized cells surrounding eachstomathat control how open or closed it is. These specialized cells are called guard cells, and they are triggered by a number of factors, such as sunlight, humidity, temperature, and internal plant chemistry To conserve water during dry times, the stomata remain closed to reduce the loss of water vapour. Due to the requirement for carbon dioxide, it is possible for the lack of moisture that forces the stomata to stay closed to prevent the process of photosynthesis from occurring. The number of stomata on the epidermal surface can tell you a lot about a plant. Usually, a high concentration of stomata indicates fast growth and a wet climate. Lower concentrations of stomata indicate lower rates of photosynthesis and growth or adaptations for dry weather. Stomata are useful to drought-threatened plants because they can close to prevent dehydration |
