1. Ch. 9.1 Cell Growth Cell Size Small 100 um
Why is it important that cells stay small?
Maintain a high surface area to volume ratio

2. Ch. 9.1 Cell Growth
Cell Size

3. Ch. 9.1 Cell Growth
In a cell, the Surface Area is the plasma membrane. The Volume is the stuff inside of the cell.

4. Ch. 9.1 Cell Growth
What are the benefits of cells staying small?

5. Ch. 9.1 Cell Growth What are the benefits of cells staying small?
Efficiently and quickly move material in or out of the cell.
Requires less energy
Easier to maintain homeostasis in smaller spaces.

6. Ch. 9.1 Cell Growth
Is it more energy efficient to heat a larger room or a smaller room in the winter time? Why?

7. Ch. 9.1 Cell Growth
Cells must stay small in order to maintain homeostasis, use less energy, and perform cellular functions quickly.

8. Ch. 9.1 Cell Growth Cell Cycle
Cells will grow to maximum size then decide to divide or stop growing.
Interphase – G1, S, G2
Mitosis – PMAT
Cytokinesis – cell splits

10. Ch. 9.1 Cell Growth
Binary Fission only occurs in Prokaryotic Cells! (bacteria)

TASKS!
Discuss why cells need to be small. Include a discussion involving what would happen if a cell was large.
List the stages of the cell cycle giving information involving each stage of Interphase.
Discuss why bacteria are able to make a person sick quickly.
