Because both simple and facilitated diffusion move from a high pressure region (gradient) to a low pressure region (gradient), so no energy must be ACTIVELY applied to complete this task. Active transport, on the other hand, requires energy because it moves molecules from a low pressure gradient to a higher one.

∙ 13y agowhen diffusion occurs it is because the substance is trying to reach equilibrium, where everything is equally spread out on both sides of a cell membrane. things naturally want to be at equilibrium in nature so this happens automatically and doesn't require any energy. and that is the definition of passive transport transportation of a substance through a cell membrane that doesn't require any energy.

What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.

Distinguish between active and passive transport?
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
Which type of transport requires assistance from membrane proteins?
cellular transport nop, is passive transport
