Energy storage opening and closing structure

During photosynthesis, leaves take in atmospheric CO 2 and release O 2 through stomata, microscopic pore structures in the leaf epidermis (singular = stoma). A pair of guard cells surrounds each stoma, and these cells control the opening and closing of the stomatal pore between them.

Stomata

Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding. It helps in transpiration and removal of excess water in the form of water vapour. Stomatal closure at night prevents water from escaping through pores. It maintains the moisture balance according to weather by opening and closing.

4.5.1.2.2: Stomatal Opening and Closure

Stomatal Closure. When water is low, roots synthesize abscisic acid (ABA), which is transported through the xylem to the leaves. There, abscisic acid causes calcium channels to open. Calcium (Ca 2 +) opens anion channels, and malate, chloride, and nitrate exit the cell.The membrane potential decreases (the difference in charge across the membrane becomes less pronounced)
