Answer 2

Tonicity is the relative concentration of the solutions that determine the direction and the extent of diffusion. Based on tonicity the three types of solutions are:

1. Isotonic Solution: The relative concentration of water molecules and the solute on either side of the cell membrane is the same. Hence there is no net movement of water molecules.

2.A hypertonic solution contains a higher concentration of solutes compared to another solution. The opposite solution, with a lower concentration or osmolarity, is known as the hypotonic solution. In biology, scientists must describe cell contents compared to the environment. If a cell is placed in a hypertonic solution, the cell will be hypotonic. If the cytosol of the cell is a hypertonic solution, it means the environment is hypotonic, or more weakly concentrated. This is of great importance because solutes and water tend to flow or diffuse along their gradients. Two solutions mixed together will eventually become a single solution. If the solutions are separated by a permeable membrane that only allows water through, the solutions will become isotonic. Isotonic solutions have equal concentrations, although they may have different volumes.

3.hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated. For cells without a cell wall such as animal cells, if the gradient is large enough, the uptake of excess water can produce enough pressure to induce cytolysis, or rupturing of the cell. When plant cells are in a hypotonic solution, the central vacuole takes on extra water and pushes the cell membrane against the cell wall. Due to the rigidity of the cell wall, it pushes back, preventing the cell from bursting. This is called turgor pressure
