Let us make in-depth study of the period of stomatal opening and types of stomatal movement with diagram. 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 and inner wall (concave) is thick. Due to endosmosis, TP [...]

The following four points will highlight the four important theories of stomatal movement. The four important theories of stomatal movement are: (1) Theory of Photosynthesis in Guard Cells (2) Starch Sugar Inter-conversion Theory (3) Theory of Glycolate Metabolism and (4) Active K+ Transport or Potassium Pump Theory and Role of Abscisic Acid or Active Potassium Pump Theory. Many theories have [...]
