Is chloroplast present in guard cells

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 outward like a balloon and draws the thick side along with it, forming a crescent; the combined crescents form the opening of the pore. WebBetween each pair of guard cell, a stomatal pore is present. They are covered by a layer of cuticle that is highly permeable to water vapour and polar substances. ... The product of …
