None of the above

Detailed explanation-1: -Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP. They also use pumps to get molecules in or out of the cell. Passive Transport does NOT use energy to transport molecules across the membrane.
Detailed explanation-2: -Active transport is ATP dependent. Passive transport does not require energy. Active transport requires cell to cell communication. Passive transport does not require cell communication.
Detailed explanation-3: -Moving substances up their electrochemical gradients requires energy from the cell. Active transport uses energy stored in ATP to fuel this transport. Active transport of small molecular-sized materials uses integral proteins in the cell membrane to move the materials: These proteins are analogous to pumps.
