potassium ion theory in simple scentence

Answer 1

Potassium ion theory was introduced by livette in 1974...

Answer 2

Answer:

Potassium ion concentration theory is a theory that explains the turgidity of the guard cell that surrounds stomata . The turgidity of the guard cell results in the opening of stomata during the daytime which aids in the diffusion of carbon dioxide inside the stomata . The carbon dioxide helps in photosynthesis .

Explanation:

During the daytime , the guard cells perform photosynthesis which leads to the activation of the A.T.P molecules . These A.T.P molecules are responsible for active transportation of the potassium ions from the surrounding of the guard cell towards the inner portion of the cells . This increases the osmotic pressure of the guard cell which becomes a hypertonic solution consisting of more number of solutes than the surrounding cells . This leads to endosmosis and water enters into the cell which makes the cells turgid . Due to this mechanism , the guard cells open up . Active transport is defined as the transportation of any substance from low concentration to high concentration using energy from the cell and through a living membrane .
