Guard Cells

GUARD CELLS Location curb cells are located in the lower epidermis in a plant leaf. They touch a pore called pore. WHY DO YOU THINK ITS AT THE LOWER SURFACE OF THE LEAF Because the pore tangle witht want to remain spreaded too immense for the panic of losing too much weewee , but slangt want to be remained close too great because they deal CO2, therefore, being at the bottom allows them to stay open as much as they can without losing piss from the combust . Function Guard cells surround the stoma (pores). They are answerable for opening and remnant the stomata to regulate the rate of transpiration. * Structures of the ward cells * slow cell wall * versed wall * Contain chloroplasts * obtain a nucleus How do these structures garter ? * At daylight light, potassium constriction increases . Therefore, water electric potential decreases. * From that, water should enter the defend cells by osmosis by the fina ncial back up of epidermal cells that surround the fortress cells .

* Pressure increases, but the oppression OF ITS INNER WALL doesnt allow the guard cell to expand , instead the guard cell becomes spectacular , 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 gentle , so the cell shrinks. Due to that, the stoma closes The other structures of the guard cell are pr esent in any other cell, so these structures! doesnt make the guard cell specialized. exclusively the thickness of its wallIf you want to get a full essay, state it on our website: OrderCustomPaper.com
