These plants are known as night bloomers They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf. During the day, photosynthesis requires that the leaf mesophyll be exposed to the air to get CO2. Stomata can not be closed in the daytime, because the plant has to intake carbon dioxide for the process of photosynthesis. When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. It helps in removing water from the leaves. That's why it is called C3 photosynthesis.

Suggest Corrections. Due to this, the process of photosynthesis would not take place and plant will die due to excess water and no food. Guard cells usually keep stomata open during the day and closed at night because during the night there is no sunlight for photosynthesis. What are various methods available for deploying a Windows application? Without oxygen or carbon dioxide present, neem trees provide the necessary defense against air pollution.
