When plant cells are in a hypotonic solution, such as fresh water, the arge central vacuole gains swater and exerts pressure called 7, when plant cells are in a hypertonic solution such as 10% NaCl, the central vacuole loses water and the cytoplasm including the chloroplasts pulls away from the cell wall. This is called 8. Which solute diffused across the dialysis membrane from the bag to the 9. Explain why the water level in the thistle tube rose beaker? Notes comments : E-::Explanation / Answer
1) In a hypotonic solution the concentration of solutes outside the cell is less than the concentration of solutes inside the cell.
2) In an isotonic solution the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.
3) A hypertonic solution has a higher concentration of solutes outside a cell than inside the cell.
4) Red blood cell shrivels due to loss of water, a process called crenation and red blood cell fills to bursting due to gain of water, a process called hemolysis.
5) Diffusion is the spontaneous movement of particles from an area of high concentration to an area of low concentration.
6) When plant cells are in a hypotonic solution, such as fresh water, the large central vacuole gains water and exerts pressure called turgor pressure.
7) When plant cells are in a hypertonic solution such as 10% NaCl, the central vacuole loses water, and the cytoplasm, including the chloroplasts, pulls away from the cell wall. This is called plasmolysis.
8) There will be no solute to diffuse across the dialysis membrane from the bag to the membrane.
9) In terms of solvent concentration, water moved from the area of higher water concentration to the area of lower water concentration across a differentially permeable membrane.
