6
Q
Osmosis
A
Movement of water molecules from a region of high water concentration to a region of low water concentration through a semi-permeable membrane
7
Q
Turgor pressure
A
The pressure of the content of a cell against its cell wall
8
Q
Plasmolysis
A
The loss of a water from the cytoplasm and the movement of the cell membrane away from the cell wall
