Diffusion is a type of passive transport because it does not require the cell to expend ATP. This means that diffusion is considered a type of passive transport. This means that diffusion is considered a type of passive transport. The cell can be the animal, plant or prokaryote cells. Diffusion does not use ATP because it needs no energy to move molecules from one area to another space in which they are low density. It has been seen as an important part of cellular respiration and photosynthesis for animals and plants respectively. It also helps maintain homeostasis in some liquids by moving water through their systems at rates proportional to demand but always counteracting osmosis (the change in concentration between two areas). The process works best when there is a difference in concentrations on either side creating gradients with higher densities on the outside than inside such as blood flowing into cap
