Open stomata at night

Open stomata at night refers to the process where tiny pores on plant leaves, called stomata, remain open during nighttime. This allows the plant to take in oxygen and release carbon dioxide, supporting respiration, the process that provides energy. While most plants close stomata to conserve water during dry or hot conditions, some, like succulents or plants in humid environments, keep them open at night to optimize gas exchange without losing excessive moisture. This nighttime opening helps plants efficiently maintain their metabolic functions and adapt to their specific environmental conditions.
