A faster drought response means that less water is lost and the survival rate of the plants is increased. In plants, a stoma is a tiny pore in the surface of a leaf that is used for gas exchange. 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. 2.3k VIEWS. Here are some important diagrams for CBSE class 10 Biology. The structure and function of Stomata. Photosynthesis is the process of absorbing energy from sunlight and using it to produce food in the form of sugars.Leaves make it possible for plants to fulfill their role as primary producers in food chains. While hydrogen is combined with carbon dioxide and used by the plant to produce its food, oxygen―being a by-product of the entire process―is released into the atmosphere through the stomata.
