WebNov 13, 2024 · What is the function of guard cells of stomata Class 7 answer? Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. ... Stomata are crucial for a plant ’s life functions because they allow carbon-containing carbon dioxide gas to enter the plant’s tissues. … Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it. As water enters the cell, the thin side bulges … See more Guard cells are specialized plant cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore. … See more Ion uptake into guard cells causes stomatal opening: The opening of gas exchange pores requires the uptake of potassium ions into guard cells. Potassium channels and … See more Guard cells perceive and process environmental and endogenous stimuli such as light, humidity, CO2 concentration, temperature, drought, and plant hormones to trigger cellular responses resulting in stomatal opening or closure. These … See more Water stress (drought and salt stress) is one of the major environmental problems causing severe losses in agriculture and in nature. See more Vacuoles are large intracellular storage organelles in plants cells. In addition to the ion channels in the plasma membrane, vacuolar ion channels have important functions in … See more During the development of plant leaves, the specialized guard cells differentiate from “guard mother cells”.
