Question

What happen when a rbc is kept in concentrated saline solution

Answer 1

Osmosis: movement of water from its higher concentraton to its lower concentration,through a semi permeable membrane.

Endosmosis:movement of water into the cell
Exosmosis:movement of water out of the cell.

If RBC cell are kept in saline solution, they gets shrunken,as water moves from the RBC cells into the saline solution.i.e they undergo exosmosis.

NOTE:
# only concentration of water is taken into consideration.
# osmosis occurs only through a semi permeable membrane.
# exosmosis is also know as plasmolysis.

Answer 2

when rbc is kept in saline water, it will shrink. as the concentration of saline solution is higher than concentration inside the cell. thus, the water will move outside the cytoplasm and cell will shrink..........!!!
