Question

Roles of of osmosis in in organisms

Answer 1

Answer:

Explanation:

. osmosis Role in animals

. it plays key role in animal cells because they will lysed when they are placed in a Hypotonic solution.

. Some cells such as erythrocytes , will actually burst as water enters them by osmotic flow .

. Rupture of the plasma membrane by a flow of water into a cytosol is termed osmotic lysis. Consequently , it is essential that animal cells be maintained in an isotonic medium .which has a solute concentration closed to that of the cell cytosol .

. Even maintaining their cell volume.

. cells contain a large number of charge macromolecules and small metabolites that attract ions of opposite charge ( eg k ^ + ,ca^2 + , PO 4^3 ).

. Also recall that there is a slow leakage of extracellular ions , particularly Na^+ And CI  , into cells down their concentration gradient then cell must be lysed .

. To prevent this animal cells Actively export inorganic ions as rapidly as they leak in .The export of Na^+ by the APT  - powered Na ^+ /k^+ pump plays the major role in this mechanism for preventing cell swelling. If cultured cell are treated with an inhibitor that prevents production of APT ,they swell and eventually burst , demonstrating the importance of active transport in maintaining cell volume.

. osmosis is important process to plants .osmosis gain water through their roots. by osmosis water moves into plant cells to make them turgid or stiff so that they are able to hold the plant upright. and all living organisms, nutrients and minerals make their way to the cells because of osmosis. An example of osmosis can be the intake of water molecules in plants.
