Explain the differences between active and passive transport.
Active transport is the movement of molecules across a cell membrane against a concentration gradient, requiring energy and often taking place in a specific order. Passive transport, on the other hand, is the movement of molecules in the same direction as a concentration gradient, requiring no energy and often occurring randomly or more than one at a time. Active transport can be regulated, while passive transport is not. Furthermore, active transport requires more time and requires more resources from the cell.
Active transport is the process of transporting molecules across a cell membrane against a concentration gradient, requiring energy.

Passive transport is the process of transporting molecules with the help of chemical forces such as diffusion and osmosis, which does not require energy.
