Osmosis
- 10. Multiple Choice
Osmosis is the movement of _____ across a membrane.
food
energy
oxygen
water
- 11. Multiple Choice
During osmosis
water moves from high to low concentration
large or oddly shaped molecules move across a cell membrane
water moves when energy is used
proteins are built
- 12. Multiple Choice
What is the definition of Selective Permeability?
The movement of materials across the cell membrane that requires NO ENERGY from the cell.
The movement of materials through (or across) the cell membrane
The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
The movement of molecules from an area of high concentration to a area of low concentration
- 13. Multiple Choice
Which cell is placed into a hypotonic environment?
A
B
C
D
- 14. Multiple Choice
Why did the red blood cell shrink?
It was placed in a hypotonic solution
It was placed in a hypertonic solution
It was placed in an isotonic solution
The oxygen left the cell
- 15. Multiple Choice
Which type of cell transport occurs when a cell's membrane folds inward to bring materials into the cell?
Endocytosis
Pinocytosis
Exocytosis
Phagocytosis
- 16. Multiple Choice
What would happen to a cell placed in a hypotonic solution?
Water would move out of the cell causing it to shrink
Salt would move out of the cell causing it to shrink/
Water would move into the cell causing it to swell
The cell would remain the same size.
- 17. Multiple Choice
What type of transport occurs when a large cell consumes a smaller cell such as a bacterium?
Endocytosis
Pinocytosis
Exocytosis
Phagocytosis
- 18. Multiple Choice
What transport occurs when fluid and solute is ingested into a cell by budding of small vesicles from the cell membrane?
Endocytosis
Pinocytosis
Exocytosis
Phagocytosis
- 19. Multiple Choice
How does particle size affect a molecule's ability to move across a cell membrane?
It is easier for small molecules to diffuse across the cell membrane
It is easier for large molecules to diffuse across the cell membrane
Particle size is not important
Particle size is not as important as shape when moving across the membrane
- 20. Multiple ChoiceThe cell membrane is selectively permeable, which means...All materials can enter and leave the cellCertain things can enter while others cannotThe cell manually sorts through all materialsOnly certain cells can interact with the cell.
