Cell Transport Review

Which of the following terms refers to a membrane allows some molecules to pass through while blocking other molecules?

• Homeostatic
• Selectively permeable
• Hydrophobic
• Passively permeable

If the water concentration in a cell is 90% and the water concentration outside the cell is 95%, what direction will the water move?

**Remember: the water follows the solute

• Into the cell

• Out of the cell

• The water will not move

Which type of solution makes a cell shrink?

• Hypotonic

• Hypertonic

• Isotonic

What type of transport moves molecules from areas of lower concentration to areas of higher concentration?

• Passive
• Active

What type of transport does not require the use of ATP (energy)?

• Passive
• Active

By which process are large molecules brought into a cell through a vesicle?

• Endocytosis
• Exocytosis
• Osmosis
• Diffusion

In which type of solution is the concentration of solute molecules equal on both sides of the membrane?

• Hypotonic
• Hypertonic
• Isotonic
