Movement through Cell Membranes Flashcards
1
Q
Osmosis
A
The movement of water molecules from an area of high concentration to a region of low concentration across a semi-permeable layer.
2
Q
Diffusion
A
The passive movement of particles from a region of high concentration to a region of low concentration.
3
Q
Passive
A
No energy is required.
4
Q
Crenation
A
The process when water leaves the cell by osmosis.
5
Q
Selectively permeable
A
Membranes can choose to allow or block materials to enter or exit a cell.
6
Q
Turgor
A
The pressure of the contents of a cell against its cell wall. Applies to any organism with a cell wall.
7
Q
Plasmolysis
A
The process of water loss from a plant cell.
