Active Transport
Diffusion is the process the carries materials across the plasma membrane. The diffusion cannot move across water.
The diffusion is what carries materials across the plasma membrane. This does not mean the diffusion can move across water.
Active Transport
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
as the concentration gradient increases at the solute side. make the question more clear.
It's Active Transport.
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
The transport of a substance across the cell membrane against its concentration gradient is called active transport.

active transport
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.

The transport of a substance across the cell membrane against its concentration gradient is called active transport.
concentration gradient moves from high to low until equilibrium is reached.
When the concentration gradient is 0, no flow is allowed to go through the cell wall. To get motion through a membrane, the concentration gradient must be higher than 0.
