Q
Passive transport
A
Movement of dissolved materials across a cell membrane without using the cell’s energy
3
Q
Diffusion
A
The process by which molecules move from an area of higher concentration to lower concentration
4
Q
Osmosis
A
The diffusion of water molecules across a selectively permeable membrane
5
Q
Active transport
A
The movement of materials across a cell membrane using cellular energy
6
Q
Endocytosis
A
when the cell membrane changes shape and engulfs the particle
7
