Which statement best describes diffusion?
Which statement best describes diffusion?
- Movement of particles across a cell membrane without the use of energy. (correct)
- Diffusion is only relevant for waste products, not nutrients.
- Movement of particles across a cell membrane requiring energy.
- Movement of molecules from low concentration to high concentration.
What is the main difference between passive transport and active transport?
What is the main difference between passive transport and active transport?
- Passive transport moves particles from low to high concentration, while active transport moves particles from high to low concentration.
- Passive transport is faster than active transport.
- Active transport only involves diffusion, while passive transport involves osmosis.
- Active transport requires the cell to use energy, while passive transport does not. (correct)
