Explanation:
Endosmosis is the movement of water from outside to inside of the cell. In hypotonic solution, concentration of the solvent is high outside the cell. Therefore, water/solvent enters the cell causing the contents of the plant cell to press against the cell wall. In hypertonic solution, exosmosis will take place, i.e. the solvent/water will move from inside to outside of the cell.

Exosmosis : The water or solvent leaves the cells.
Endosmosis: Water or solvent moves into cells.
Explanation:
Endomosis:
- Endosmosis is a kind of osmosis in which the solvent flows towards the inner of a vessel or cell. When the water potential outside the cell is higher than in the cytoplasm, the phenomena occurs.
- As a result, the solute concentration in the solution surrounding the cell is lower than the cytoplasmic concentration. In endosmosis, water molecules flow within the cell via the cell membrane (which is semipermeable in nature), causing the cell to enlarge and become turgid.
Exosmosis:
- The exosmosis process refers to the type of osmosis in which the direction of the water or solvent is outside a container or cell. It occurs when the water potential outside the cell is lower than inside the cells.
- Therefore, the concentration of the solute in the solution surrounding the cell is greater than the concentration of the solute in the cytoplasm.
- During exocytosis, water molecules exit the cell through the semi-permeable cell membrane. Due to this, cells shrink, which leads to plasmolysis.
