Differences between plasmolysis and haemolysis?

Plasmolysis is an effect of osmosis in plants. Osmosis is the net diffusion of water across a selectively permeable membrane, such as a cell membrane, from an area of higher water concentration to an area of lower water concentration.

Hemolysis is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid

Both are cause by osmosis
