multiple-choice question
what type of transport is simple diffusion?
active transport
passive transport

Explanation:

Simple diffusion is a process where substances move across a cell membrane from an area of higher concentration to lower concentration, following the concentration gradient (the "flow" referenced in the image). It does not require energy input (like ATP) or transport proteins, which defines passive transport. Active transport, by contrast, requires energy to move substances against their concentration gradient.

Answer:

passive transport
