The best answer is (3).
Guard cells help regulate water loss by controlling the opening and closing of stomata which facilitates gas exchange and transpiration in plants.
Guard cells are able to control the opening and closing of stomata by changing shape. The guard cells take in potassium ions which causes water to diffuse into them by osmosis. The cells then swell and become bowed. When this happens, they bend way from each other thereby opening the stomata.
When they lose the potassium ions, water diffuses out by osmosis and the cells become flaccid and less bowed thus closing the stomata between them.

Answer:
Adenosine triphosphate or ATP is the energy-providing molecule of the organisms which produce energy during the metabolic process. Therefore this is also considered as the energy currency of the cell.
As a biomolecule, it is made up of three components: a ribose sugar, adenine nitrogenous base and three phosphate groups. Its adenine base is attached to the 9th nitrogen atom of the 1′ carbon of the sugar. and three phosphate group are attached to the 5' carbon atom of the sugar.
High energy is stored in the three phosphate bonds which when broken down to adenosine diphosphate and monophosphate releases energy. New ATP is generated through the process of phosphorylation in mitochondria and chloroplasts in plants. The ATP production reaction is catalyzed by ATP synthase
