Question

can we call diffusion passive transport if so how

Answer 1

In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we'll look in more detail at membrane permeability and different modes of passive transport.

Answer 2

Yes as., Diffusion is a means of passive transport that involves movement of particles from high concentration to low concentration across a semi permeable membrane. It does not need any external source of energy to occur.
