Biology: Diffusion
Osmosis Definition:
The movement of water molecules through a solute.
Endocytosis Definition:
The process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell.
Facilitated Diffusion Definition:
The process of molecules or ions that move across/through a membrane.
Exocytosis Definition:
The process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.Feb 24, 2012

Active Transport Definition:
The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Osmosis Example:
Water
Diffusion Definition:
When molecules move from High concentration to low concentration and never stop moving
