Answer 1

Difference: Active transport uses cellular energy (ATP) to move substances, often against their concentration gradient. Passive transport does not use ATP and moves substances down their concentration gradient.

Matches:
- Active transport: requires ATP energy; exocytosis (and pumps, endocytosis)
- Passive transport: facilitated diffusion; osmosis (and simple diffusion)
