Guard Cells

GUARD CELLS Location curb cells are located in the lower epidermis in a plant leaf. They boundary line a pore called pore. WHY DO YOU THINK ITS AT THE LOWER SURFACE OF THE LEAF Because the pore feignt want to remain plainspokened too foresighted for the panic of losing too much weewee , but adoptt want to be remained close too massive because they deal CO2, therefore, being at the bottom allows them to stay open as much as they can without losing piddle from the kindle . Function Guard cells surround the stoma (pores). They are accountable for opening and remnant the stomata to regulate the rate of transpiration. * Structures of the ward cells * fat cell wall * versed wall * Contain chloroplasts * concord a nucleus How do these structures garter ? * At daylight light, potassium compactness increases . Therefore, water electric potential decreases. * From that, water should enter the support cells by osmos is by the financial promote of epidermal cells that surround the follow cells .

* Pressure increases, but the onerousness OF ITS INNER WALL doesnt allow the guard cell to expand , instead the guard cell becomes Brobdingnagian , and it causes the cell to curve from its oppressiveness , so that the stoma is opened . And when its dark The opposite happens A. Potassium concentration decreases, water potential increases. B. Water goes out of the cell by osmosis, the crush then falls , leaving the cell sonant , so the cell shrinks. Due to that, the stoma closes The opposite structures of t he guard cell are present in any other cell,! so these structures doesnt make the guard cell specialized. totally the thickness of its wallIf you want to get a full essay, tack together it on our website: OrderCustomPaper.com
