》》ENDOSMOSIS《《

■In endosmosis , movement of water molecules occurs from the surrounding environment into the cell due to a difference in water potential along the cell membrane. The water potential of the surrounding environment is higher than the water potential within the cell in endosmosis .

■In simple terms , endosmosis is a movement of water into the cell through semi - permeable cell membrane . Concerning the solute concentrations , cell cytosol has a higher solute concentration than the cell surroundings . The difference in water potential and difference in spite concentrations involve in building up of a potential gradient that results in endosmosis.

□EXAMPLES □

●When we put raisin inside a bowl of water , the raisin swells up after a few minutes because there is higher concentration inside the raisin .

●Absorption of capillary water from soil by root .

●Passing of water through the Xykem vessel.

》》EXOSMSIS《《

■In Exosmosis , the water that is present in the cytosol is moved out from the cell due to water potential gradient built across the cell and surrounding environment. Here , the water potential of cell is said to be higher concerning the surrounding environment . Therefore, The water moves from the place of higher water potential ( cell cytosol) to a place of lower potential (solution).

■During exosmosis , the solute concentration in the cell is lower than the outside environment . The difference in water potential and solute concentration cause the built up of a potential gradient that results in occurrence of exosmosis in the cell .

□EXAMPLES □

■Movement of water out from the raisins when kept in hypertonic solution .

■Passage of water from root hair cells to cortical cells of root .

■When grapes are kept in higher concentrated sugar solution they become flaccid.

hope it helps u dear ^_^
