Question

what would happen when eukaryotic cells are placed in hypertonic hypotonic and isotopic solutions?

Answer 1

When eukaryotic cells are placed in

Hypertonic solution - The cell will lose its water due to the process of photosynthesis.

Hypotonic solution - The cell will gain water due to the process of photosynthesis.

Isotopic solution - The cell will have no change.

Answer 2

Understanding osmosis at first .

The movement of solvent molecules from its region of higher concentration to lower concentration through a semi permeable membrane is called osmosis.
It is of 2 types--

1) Endosmosis - From outside to inside
2) Exosmosis - From inside to outside

Now if a cell is placed -

1) Hypertonic solution - The cell shrinks as water moves outside due to high concentration of water inside the cell.This occurs due to Exosmosis.

2) Hypotonic solution - The cell swells up as water moves inside due to low concentration of water inside the cell.This occurs due to Endosmosis.

3) Isotonic solution - The cell remains same due to same concentration of water both outside and inside the cell.
