Stomatal Mechanism: How Plants Control Gas Exchange
Dec 30, 2024 · Explore the role of stomata in plants, emphasizing the process of opening and closing for efficient gas exchange and water conservation.
Explain the Mechanism of Stomatal Opening. - Owlgen
Stomata open when guard cells take up water, leading the cells to bow outward (e.g., kidney bean shape). When the cells lose Water, they become more flaccid and collapse inward, thus decreasing the size of the opening.
Period of Stomatal Opening and Types of Stomatal Movement
The opening and closing of stomata is known as stomatal movement. When guard cells are turgid, stomata open and when flaccid, stomata close. The outer wall (convex) of guard cell is thin …
