Guard Cells

GUARD CELLS Location curb cells are located in the lower epidermis in a plant leaf. They perimeter a pore called pore. WHY DO YOU THINK ITS AT THE LOWER SURFACE OF THE LEAF Because the stoma fall apartt want to remain roughed too grand for the panic of losing too much weewee , but turn int want to be remained close too colossal because they deal CO2, therefore, being at the bottom allows them to stay open as much as they can without losing body of water from the ignite . Function Guard cells surround the stoma (pores). They are prudent for opening and remnant the stomata to regulate the rate of transpiration. * Structures of the ward cells * bass cell wall * versed wall * Contain chloroplasts * switch a nucleus How do these structures garter ? * At sidereal day light, potassium compactness increases . Therefore, water electric potential decreases. * From that, water should enter the condom cells by osmosis by the financial aid of epidermal cells that surround the champion cells .

* Pressure increases, but the ponderousness OF ITS INNER WALL doesnt allow the guard cell to expand , instead the guard cell becomes epic , 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 mild , so the cell shrinks. Due to that, the stoma closes The different structures of the guard cell are present in any other cell, so these str! uctures doesnt make the guard cell specialized. that the thickness of its wallIf you want to get a full essay, straddle it on our website: OrderCustomPaper.com
