Question

What in plant cells contributes to the solute potential?


Open in App
Solution

Solute potential:

  1. The solute potential is defined as the amount of pressure required to stop water from passing through a semipermeable membrane into a solution.
  2. With an increase in solute concentration, solute potential declines; this results in a drop in total water potential.
  3. In a plant cell, the solute potential, also known as the osmotic potential, is negative, while it is zero in purified water.

Plant cell's contribution to solute potential:

  1. Plant cell forms the basis of plant tissue.
  2. The cell wall, cell membrane, organelles, structure of cytoplasm, and cytosol form a typical structure of plant cell.
  3. The cells in plants have a large central vacuole.
  4. The contents like the vacuolar sap, contribute to the solute potential of the cell.
  5. Plant cells, as opposed to animal cells, have a cell wall that encloses the cell membrane..
