The correct statement is: "Active transport requires cell energy while osmosis does not."
Here's a brief explanation of the terms:
1. **Active Transport**: This process requires energy, typically from ATP, to move substances against their concentration gradient (from an area of lower concentration to an area of higher concentration).
2. **Osmosis**: This is the passive movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration, and it does not require cell energy.
3. **Facilitated Diffusion**: Like osmosis, this is also a passive transport mechanism that does not require energy. It involves the movement of molecules across a cell membrane via protein channels.
4. **Diffusion of gases and other small molecules**: This process occurs naturally and does not require energy, as molecules move from areas of higher concentration to areas of lower concentration.
Thus, the distinction between active transport requiring energy and osmosis being a passive process is key.
