How is active transport different from passive transport? A Both active and passive transport occur within plant cells, but only active transport occurs within animal cells.
B. Passive transport uses energy to move materials across a cell membrane against a concentration gradient, while active transport moves materials across a cell membrane in the direction of a concentration gradient, without using energy.
