Which of the following element is responsible for maintaining turgor in cells. (A) Potassium (B) Sodium (C) Magnesium (D) Calcium
Option A. Potassium (K) is responsible for maintaining a turgor. Turgor pressure is also defined as hydrostatic pressure as it measures the pressure created by a fluid to a certain point within itself when at equilibrium. The osmotic flow of water creates turgor pressure which is seen in fungi, plants and bacteria. The protist consisting of cell walls also shows turgor pressure and it is not seen in animal cells due to the presence of cell walls. The cell starts lysing under too much pressure and the pressure exerted by the flow of water is known as turgidity which is caused due to the osmotic flow of water from a selectively permeable membrane.
