- 24. Multiple ChoiceWhat happens during diffusion?A. Particles move slightly but stay in almost the same place.B. Particles move to different areas but always return to their starting point.C. Particles move from an area that is more concentrated to an area that is less concentrated.D. Particles move from an area that is less concentrated to an area that is more concentrated.
- 25. Multiple ChoiceWhat material diffuses across a selectively permeable membrane from an area of higher concentration to an area of lower concentration through the process of osmosis?A. LipidB. ProteinC. SaltD. Water
- 26. Multiple ChoiceWhat is the difference between diffusion and facilitated diffusion?A. Diffusion occurs when molecules spread out by moving randomly, while facilitated diffusion occurs when protein channels help molecules move across the cell membrane.B. Facilitated diffusion occurs when molecules spread out by moving randomly, while diffusion occurs when protein channels help molecules move across the cell membrane.C. There is no real difference between the two, except that facilitated diffusion happens slightly faster than diffusion.D. There is no real difference between the two, except that diffusion happens slightly faster than facilitated diffusion.
- 27. Multiple ChoiceWhich of the following accurately describes facilitated diffusion?A. Facilitated diffusion is the movement of substances requiring the use of energy.B. Facilitated diffusion does not involve the movement of substances across a membrane.C. Facilitated diffusion is the movement of substances in a slower, more deliberate way than diffusion.D. Facilitated diffusion is the movement of substances that cannot directly diffuse across the cell membrane.

- 29. Multiple ChoiceEndocytosis is a process by which cellsA. bring bulk material into the cell via vesicles.B. bring bulk material into the cell via pores.C. remove bulk material from the cell via vesicles.D. remove bulk material from the cell via pores.
- 30. Multiple ChoiceWhat are the two major types of active transport?A. Molecular transport and exocytosisB. Endocytosis and bulk transportC. Molecular transport and bulk transportD. Exocytosis and endocytosis
- 31. Multiple ChoiceHow 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. Both active and passive transport occur within animal cells, but only active transport occurs within plant cells.C. 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.D. Active transport uses energy to move materials across a cell membrane against a concentration gradient, while passive transport moves materials across a cell membrane in the direction of a concentration gradient, without using energy.
