The movement of a solvent through a membrane separating two solutions of different concentrations. The solvent from the side of weaker concentration usually moves to the side of the stronger concentration, diluting it, until the concentrations of the solutions are equal on both sides of the membrane.

Give example of exosmosis and endosmosis?
endosomsi
The process of water moving out of a cell is called?
OSMOSIS More specifically: Endosmosis is the movement of water into a cell Exosmosis is the movement of water out of a cell
What happens to a cells when they are put in a higher concentration of water?
When a cell is placed in higher concentration of water then endosmosis of water in the cell takes place because in the cell water concentration is low and osmotic(solute) pressure is high so water moves from its higher concentration towards its lower concentration which means it moves inside the cell and the cell becomes turgid.
What happens to the cell when more water leaves the cell than enters it?
When a cell is placed in water , there is a possibilty of 2 processes to occur : 1. Exosmosis - IF the water has more osmotic concentration than the cytoplasm hypertonic medium ) 2. Endosmosis - If the water has less osmotic concentration than the cytoplasm (hypotonic medium )
How are the opening and stomata related to transpiration When does transpiration occur?
opening and closing of stomata occurs due to turgor changes in guard cells ....................due to exchange of gases carbon dioxide accumulate creating acidic nature resulting in favourable conditions for conversion of starch to glucose ...........glucose being soluble in water increases solute content resulting in endosmosis ..................this results in pulling apart of the opposed inner thicker walls creating an open pore in gaurd cells of stomata
What is the process swelling of raisins is known as?
endosmosis
Give example of exosmosis and endosmosis?
endosomsi
What are the five examples of endosmosis nand exosmosis?
example of exosmosis
What is the difference between endosmosis and exosmosis?
The definition of exosmosis and endosmosis is that to remind it permanently is "exo" is to exit and "endo" is to enter in.That is exosmosis is the losing of water of a cell . Endosmosis is the entering of water to a cell .== == == ==
Do wet raisins show endosmosis?
It is an example of hypotonic solution and the raisins will swell up.
What happen dry apricots are left for sometimes in pure water and later transferred to sugar solution?
first they will swell up due to endosmosis
What condition in cells versus their environments causes water to move through cell membranes?
Difference of concentration of water causes endosmosis or exosmosis .
The process of water moving out of a cell is called?
OSMOSIS More specifically: Endosmosis is the movement of water into a cell Exosmosis is the movement of water out of a cell
How will the movement of water affect a cell if it's transferred from a hypotonic solution to a hypertonic solution?
The cell will shrink in size..
Why do raisins swell up when placed in water?
Because water passes out of the raisins [region of higher concentration] into the salt solution [region of lower concentration] through the semipermeable membrane.
What forms osmosis?
the tendency of a fluid, usually water, to pass through asemipermeable membrane into a solution where thesolvent concentration is higher, thus equalizing theconcentrations of materials on either side of themembrane. the diffusion of fluids through membranes or porouspartitions. Compare endosmosis, exosmosis.
Why are plant cells selected to demonstrate plasmolysis rather than animal cells?
Plant cells are selected to demonstrate plasmolysis rather than animal cells. This because thy have the ability to absorb water through endosmosis unlike animal cells which would burst.
