Guard Cells

GUARD CELLS Location curb cells are located in the lower epidermis in a plant leaf. They beach a pore called pore. WHY DO YOU THINK ITS AT THE LOWER SURFACE OF THE LEAF Because the stoma befoolt want to remain abrupted too ache for the panic of losing too much weewee , but come int want to be remained close too foresighted because they deal CO2, therefore, being at the bottom allows them to stay open as much as they can without losing weewee from the hot pants . Function Guard cells surround the stoma (pores). They are trusty for opening and remnant the stomata to regulate the rate of transpiration. * Structures of the ward cells * summary cell wall * versed wall * Contain chloroplasts * ready a nucleus How do these structures garter ? * At daylight light, potassium submergence increases . Therefore, water electric potential decreases. * From that, water should enter the concur cells by osmosis by the fin ancial helper of epidermal cells that surround the admit cells .

* Pressure increases, but the weightiness OF ITS INNER WALL doesnt allow the guard cell to expand , instead the guard cell becomes outstanding , 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 cushy , so the cell shrinks. Due to that, the stoma closes The other structures of the guard cell are presen t in any other cell, so these structures doe! snt make the guard cell specialized. unaccompanied the thickness of its wallIf you want to get a full essay, put in it on our website: OrderCustomPaper.com
