Movement of cell against concentration gradient is called

A. Active transport

B. Diffusion

C. Osmosis

D. Passive transport

Answer: Option A

Solution(By Examveda Team)

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
