Question

membrane transport graphic organizer
type of transport: simple diffusion
image: diagram of simple diffusion across a membrane
description
active
passive

Explanation:

To determine the type (active/passive) of simple diffusion: Simple diffusion is the movement of molecules from an area of high concentration to low concentration, without energy input. Passive transport is defined as the movement of substances across a membrane without energy, while active transport requires energy. So simple diffusion is passive.

Answer:

passive
