[PDF] animal cell burst in hypotonic solution

Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic. A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution.

  • Why do animal cells burst in hypotonic solutions but not plant cells?

    Animal cells do not have a cell wall but only the cell membrane. In plant cells, a cell wall is located outside the cell membrane, which gives the cell, its structure and strength. When a cell is kept in a hypotonic medium, the cells take up water from external medium and swell up.

  • What happens when an animal cell bursts?

    Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water.
  • If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
