Question

What purpose of transportation? Where does it happen the cell

Answer 1

Materials move within the cell's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion (Figure 3). Diffusion expends no energy. On the contrary, concentration gradients are a form of potential energy, dissipated as the gradient is eliminated

Answer 2

Explanation: How do things move across a cell membrane?

Summary. Controlling the movement of things in and out of the cell is an important role of the plasma membrane. ... Osmosis is the diffusion of water molecules across a membrane. Water moves in or out of a cell by osmosis until its concentration is the same on both sides of the plasma membrane.
