Detailed explanation-1: -Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

Detailed explanation-2: -The increase in pressure makes the cell rigid. If plant cells lose too much water by osmosis they become less rigid and eventually the cell membrane shrinks away from the cell wall.

Detailed explanation-3: -Plasmolysis: Hypertonic environment or hot/dry weather conditions may cause the cells, with a cell wall, to lose water. This process eventually induces the cell membrane to collapse inside the cell wall resulting in gaps between the cell wall and cell membrane and lysis occurs as the cell shrivels and dies.

Detailed explanation-4: -Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does. This is known as a hypertonic solution. Water flows out of the cells and into the surrounding fluid due to osmosis.

Detailed explanation-5: -Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water.
