WebFeb 4, 2010 · Stomatal Mechanism of CAM Plants Light is the most important environmental factor stimulating stomatal opening. The evidence that light can induce stomatal opening in carbon dioxide concentration comes mainly from studies of the extent of opening in different wavelength of light. WebThe aforementioned details pertain to the mechanism of opening and closing of photoactive stomata (i.e., stomata that open during day time), but in some plants (e.g., succulent plants like Opuntia) stomata open during night {i.e., when light is absent). Such stomata are called scotoactive stomata.
