What are the differences between endosmosis and exosmosis?
Posted June 11, 2024

Answer
Basis of differentiation 
Endosmosis 
Exosmosis 
Definition 
Is the movement of the solvent from the surrounding environment toward the inside of a cell or substance
Is the movement of the solvent out of the cell into the surrounding environment
Direction of water flow 
Water moves into the cell 
Water moves out of the cell 
Type of solution 
Occurs when a cell or substance is placed in a hypotonic solution
Occurs when a cell or substance is placed in a hypertonic solution

Solute concentration of the surrounding environment

Solute concentration of the surrounding environment is lower than the solute concentration inside the cell
Solute concentration of the surrounding environment is greater than the solute concentration inside the cell

Water Potential

Water potential of the cytosol is lower than that of the surrounding environment
Water potential of the cytosol is greater than that of the surrounding environment
Fate of cells
Excessive water intake can cause cells to swell and potentially burst 
Excessive loss of water can cause cells to shrink or contract 

Examples

  • Raisins swell when placed in plain water 
  • Plant roots absorb water from the soil
  • Transport of water from roots to the xylem 
  • Raisins shrink when placed in a strong salt solution
  • Water flows from the root hair cells to the cortical cells of the root
