Cell Transport Notes
 Why is a cell membrane is referred to a selectively permeable?
 Why is the membrane called a fluid mosic model?
 Through which method of transport are products secreted from a cell to other parts of the body?
 Compare/contrast pino- and phagocytosis.
1. If the semipermeable membrane in the diagram to the right
allowed salt to pass through, salt would move ____________ the
cell.
2. If the membrane to the right only allows water to pass through
(and not salt), water would move ___________ the cell.
3. The movement of water in #2 is called ___________________.
4. Explain the smell of onion spreading through the room during the
plasmolysis lab.
5. Label what is
happening on the
diagram to the left.
6. Draw arrows below predicting the movement of particles or water.
Draw an arrow showing the direction salt will diffuse.
Draw an arrow showing the direction of osmosis .
7. All of the cells below are 80% water. The sugar cannot pass though the membrane. Draw an arrow to
show which way most of the water will be moving. Under the diagram, indicate whether the cell will
expand/lyse, contract, or do neither.
A
B
C
D
8. In which of the diagram(s) above are the cells hypertonic to the sugar solution? _____________
9. In which of the diagram(s) above are the cells hyportonic to the sugar solution? _____________
10. In which of the diagram(s) above are the cells isotonic to the sugar solution? _______________
