if a plant cell is placed in a hypotonic solution

If a plant cell is placed in a hypotonic solution, it means that the concentration of solutes (such as salts and sugars) outside the cell is lower than the concentration inside the cell. In this scenario:

  1. Water Movement: Due to the concentration gradient, water will move from the hypotonic solution (with lower solute concentration) into the plant cell (with higher solute concentration) through the process of osmosis.
  2. Cell Expansion: As water enters the plant cell, it will cause the cell to swell or expand. This is because the central vacuole and the cytoplasm will take in water, creating turgor pressure against the cell wall.
  3. Turgor Pressure: The increased turgor pressure inside the cell pushes the cell membrane against the cell wall, creating a firm and rigid structure. This pressure is essential for maintaining the shape and structure of plant cells, as well as providing support for the entire plant.
  4. Plasmolysis Prevention: Plasmolysis, the shrinking of the cell contents away from the cell wall due to water loss, is prevented in hypotonic solutions because water enters the cell, maintaining turgor pressure and preventing the cell membrane from detaching from the cell wall.

Overall, when a plant cell is placed in a hypotonic solution, it tends to swell and become turgid due to the influx of water through osmosis.
