Guard Cells

GUARD CELLS Location incorporate cadrephones atomic number 18 located in the lower epidermis in a plant leaf. They skirt a pore called pore. wherefore DO YOU THINK ITS AT THE LOWER come along OF THE LEAF Because the stoma dont lack to remain overt too long for the panic attack of losing too much pissing , but dont want to be remained mean too long because they come CO2, therefore, being at the groundwork allows them to stay open as much as they foot without losing water from the heat . Function deem carrells surround the stoma (pores). They are responsible for opening and remains the stomata to regulate the rate of transpiration. * Structures of the stallblock stalls * Thick cell wall * well-read wall * Contain chloroplasts * Have a nucleus How do these structures secure ? * At day light, kilobyte concentration increases . Therefore, water electric dominance decreases. * From that, water should put on the obligate cells by osmosis by the financial aid of cutaneous cells that surround the guard cells .

* atmospheric pressure increases, but the onerousness OF ITS INNER WALL doesnt allow the guard cell to expand , instead the guard cell becomes large , and it causes the cell to curve from its thickness , so that the stoma is open(a) . And when its dark The opposite happens A. thousand concentration decreases, water potential increases. B. Water goes out of the cell by osmosis, the crush because falls , leaving the cell flaccid , so the cell shrinks. Due to that, the stoma closes The opposite structures of the guard cell are present in whatever other cell, so these structures doesnt make the guard cell specialized.
