When guard cells are turgid, stomatal pore is open while in flaccid conditions, the stomatal aperture closes. Diagram of Stomata. The guard cells control the opening and closing of stomata. They regulate the process of transpiration and gaseous exchange. Generally stomata are open during the day and close at night. The turgor changes in the guard cells are due to entry and exit of water into and out of the guard cells. Find an answer to your question Draw diagram of a stomata when it is open 1.

As the density of CO 2 retards gradually, the stoma begins to open and it opens gradually lengthwise until the density of CO 2 becomes .01%. 2.transpiration. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. Stomata open and close to allow the intake of carbon dioxide and the discharge of oxygen. (ii) Sayre (1926) observed that stomata open in neutral or alkaline pH, which prevails during day time due to constant removal of carbon-dioxide by photosynthesis.
