Question

what would will happen when eukaryotic cells are placed in hypertonic,hypotonic and isotonic solutions

Answer 1

In hypotonic solution the  cell would swell up due to endosmosis
In isotonic solution the Cell will remain of the same size
In hypertonic solution the cell will shrink due to exosmosis

Answer 2

Eukaryotic cells when placed in different solutions would behave in the following ways:

i) In hypertonic solution - Cells placed in hypertonic solution i.e., an environment where the solute concentration is more outside than inside the cells, water from the cells will move out and the cells will shrink.

ii) In hypotonic solution - Cells wen placed in a solution where the solute concentration outside is less than inside the cells, water from outside will enter the cells and the cells will become turgid. Sometimes, it can also burst.

iii) In isotonic solution - Cells when placed in a solution where the solute concentration outside and inside the cells is same, the water movement in both directions will be balanced and the cells will retain their original shape.
