Answer:
C. K+ ions flow out the the guard cells and water flows out the cells.
Explanation:
The turgidity of the guard cells allows the opening and closing of the stomata. This is especially necessary when it comes to water conservation in plants. In order for the cells to become turgid or flaccid, there must be the influx and out ward movement of water via osmosis.
In order for this the occur the osmotic pressure of the cellular environment must change and this is done by changing the solute concentration.
The pumping in of K+ ions out the cell allows the solute concentration to decrease and this in turn encourages the movement of water across a concentration gradient through a semi-permiable membrane.
The water leaves the guard cells and they become flaccid. This causes the stomata to be covered.
