Cell Transport
Movement between cells

2. Cell Transport
It’s all about homeostasis  maintaining balance or a constant environment

4. Cell transport Practice Problems
KEY THINGS TO REMEMBER:
Water moves from a high to low concentration (osmosis).
The plasma membrane is semi-permeable.
Water follows salt!

5. Cell transport examples
1.Given the following internal and external conditions, what would happen to the following cell?
20% H20
80% H20
The cell will shrink!

6. Cell transport examples
2.Given the following internal and external conditions, what would happen to the following cell?
.5% NaCl
5% NaCl
The cell will grow (water follows
the salt inside of the cell)!

7. Cell transport examples
Given the following internal and external conditions, what would happen to the following cell?
50% H20
50% H20
The cell will stay the same!

8. Cell transport examples
Given the following internal and external conditions, what would happen to the following cell?
70% H20
30% H20
The cell will grow!

9. Cell transport examples
Given the following internal and external conditions, what would happen to the following cell?
1% NaCl
.1% NaCl
The cell will shrink (water follows
the salt outside of the cell)!
