How much do you know about osmosis

Study Notes

Diffusion is the interpenetration of molecules of two gases or liquids of different concentrations.
Permeable membranes allow all molecules to pass from one side to another, while semi-permeable membranes allow only solvent molecules to pass.
Osmosis is the physical phenomenon of mixing two solutions or miscible gases, with different concentrations, separated by a semipermeable membrane.
The main laws of osmosis include osmotic pressure being exerted only on crystalloid substances, electrolyte crystalloids having a higher osmotic pressure than non-electrolytic crystalloids, and osmotic pressure being directly proportional to the concentration of the solution and inversely proportional to its volume.
The plasma membranes of the cell (plasmalemma and tonoplast) show relative and selective semi-permeability.
The turgor state of cells contributes to the mechanical support of herbaceous plants.
Plasmolysis is the separation of the plasmalemma from the pectocellulosic membrane and can be used as an indication of cell viability.
The plasmolytic method can be used to determine the osmotic pressure of the cell juice.
Plant cells in meristematic tissues that have very small vacuoles or those in dry seeds that lack vacuoles are supplied with water through the imbibition phenomenon.
Imbibition is the physical phenomenon of water penetration into the colloidal gels of the cell.

Imbibition is the basis of water absorption and swelling of seeds.
Leguminous seeds have the highest imbibition capacity.
Mature cells absorb water by osmosis.
Land plants cannot reach maximum turgor due to transpiration.
The suction force of a cell depends on its degree of water saturation.
Plants absorb water and mineral substances from the soil.
Water regime is important for normal turgor in cells.
Drought conditions can lead to death of plants.
Water content varies depending on species, organ, and tissue.
Water content in plants varies with climatic factors and seasons.
