What if guard cells stop working
Answers
They are like an inflatable set of doors that make the opening between the two cells wider or narrower. The guard cells change shape depending on the amount of water and potassium ions present in the cells themselves.
Guard cells take in potassium ions and water diffuses into the cells by osmosis.
Osmosis is movement of water from an area of low concentration of solute to an area of high concentration of solute.
If gaurd cells stop working, then the regulation of transpiration cannot be done as the stomata cannot open or close.
EXPLANATION:
Guard cells are found in the stomata of leaves of the plant. They are basically turgid, swollen and have large stomatical opening. These cells are responsible for maintaining the gas exchange.
They make the stomata to open during the morning and close in night. In the morning they help in photosynthesis. If the stomata are closed in night due to flaccid form of cell causing the very little gas exchange but would be great loss of water.
