5.5 Osmosis Flashcards
1
Q
Water potential
A
Pressure exerted by water molecules as they collide with a membrane or container
2
Q
Hydrostatic pressure
A
Pressure of solution in a closed system eg. A cell
3
Q
Cytolysis
A
Occurs when a cell bursts due to an osmotic imbalance causing excess water to diffuse into the cell
4
Q
Crenation
A
Formation of uneven notched corners on cells caused by osmosis water loss
5
Q
Turgor
A
Pressure exerted by fluid in a cell that presses rhe cell membrane against the cell wall
6
Q
Plasmolysis
A
Contraction of protoplasm of a plant cell caused by loss of water in the cell
7
Q
