1. Large cells cannot transport nutrients across membrane
A group of smaller cells has a larger surface area than a single cell with the same volume...

2. Remember, cells must use diffusion and osmosis to obtain important nutrients, like oxygen and glucose

3. Interphase – cell copies DNA and prepares for division
Cell Division - process by which a cell splits into two identical daughter cells
Occurs in two main phase: 
Interphase – cell copies DNA and prepares for division
Mitosis – chromosomes separate into two new cells

4. What are chromosomes? DNA containing cell’s genetic code
Each chromosome has a matching pair (homologous)
During interphase, each chromosome copies itself

5. Life Cycle of the Cell Mitosis = nuclear division
Mitosis is followed by cytokinesis (cell division)
The steps of mitosis ensure that each new cell has the exact same number of chromosomes as the original
Interphase = growth phase, differentiation occurs

6. The Cell Cycle Interphase (longest phase)
G1 - first growth (gap) phase
Synthesis - DNA makes a copy
G2 - second growth (gap) phase, preparing for mitosis
Mitosis - nucleus divides, ensuring each new cell has the exact number of chromosomes as parent

7. Interphase • Prophase • Metaphase • Anaphase • Telophase
IPMAT

8. 1. chromosomes visible (chromatids)
2. centrioles migrate to the poles
3. nuclear membrane disappears
4. nucleolus disappears
5. spindle forms

9. 1. chromosomes line up on the equator, spindle attaches

10. 1. chromatids separate and move to opposite poles

11. 1. chromosomes disappear • chromatin
2. nuclear membrane reforms
3. nucleoli reappears
4. spindle disappears
5. centrioles duplicate

12. - division of the cytoplasm to form 2 new daughter cells
- organelles are divided
- daughter cells are genetically identical
Cells return to interphase
