active transport
active transport
You'll have to be more specific. It can be either. The distinguishing feature is that active transport requires energy to occur, passive does not
Movement of particles .
active transport
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.

Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
Active transport requires energy while passive transport does not.
