In biology, transport refers to the act or the means by which a molecule or ion is moved across the cell membrane or via the bloodstream. There are two types of transport in this regard:
(1) passive transport (2) active transport.
- Passive transport is a kind of transport by which ions or molecules move along a concentration gradient, which means movement from an area of higher concentration to an area of lower concentration.
- Active transport is a kind of transport wherein ions or molecules move against a concentration gradient. This means the movement is from an area of lower concentration to an area of higher concentration
