Last Answer : answer:
Description : Stomatal opening is based on (1) Exosrnosis (2) Endosmosis (3) Plasmolysis in guard cells (4) Decrease in concentration of cell sap
Last Answer : (2) Endosmosis Explanation: According to the K+ ion theory the guard cells absorb K+ ions from the cells around them as they produce ATP (due to photosynthesis) and become ... guard cells become turgid and the stomata opens. Decreasing light intensity and photosynthesis causes Stomatal closing.
Description : Stomatal opening is based on (1) Exosmosis (2) Endosmosis (3) Plasmolysis in guard cells (4) Decrease in concentration of cell sap
Last Answer : Endosmosis

Last Answer : (A) 4.4 KPa
Description : How do I lose my incipient belly fat?
Last Answer : Sit-ups work the wrong muscles. Do leg lifts (http://www.youtube.com/watch?v=fJ0u7B0fxAU), and run. I know running sucks, but it’s the only way to burn the fat. Obviously cut the sweets out of your diet if you’re committed to this.

Last Answer : When a living plant cell loses water through osmosis there is shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as Plasmolysis.

Description : Cell becomes turgid because of - (1) Plasmolysis (2) Exosmosis (3) Endosmosis (4) Diffusion
Last Answer : (3) Endosmosis Explanation: When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is ... become "turgid" i.e. swollen and hard. So it is because of endosmosis that cell becomes turgid.
