1. Cell Reproduction
Prokaryotes Bacteria
Eukaryotes Plants & animals

2. Eukaryotes Contain a nucleus & membrane bound organelles
Asexually reproduce cells by mitosis

3. Cell Cycle Stages in growth & division Interphase: M Phase (Mitosis)
G1 Phase
S Phase
G2 Phase
M Phase (Mitosis)
Cytokinesis

4. Interphase

5. Interphase: G1 PHASE S PHASE G2 PHASE First growth stage
Cell increases in size
Cell prepares to copy its DNA
DNA replication
Chromosomes duplicate
Cell continues to grow

6. M Phase (MITOSIS) (nuclear division) Phases: Prophase Metaphase
Anaphase
Telophase

7. Cells Undergoing Mitosis

8. Prophase DNA becomes visible as chromosomes
Nuclear membrane disappears
Spindle begins to form

9. Human Chromosomes (image is a Karyotype)

10. Steps in Metaphase Spindle fibers attach to each chromosome
M = middle
Spindle fibers attach to each chromosome
Cell aligns its chromosomes in the middle of the cell

11. Metaphase

12. Anaphase
A= Apart
Cell chromosomes are separated

13. Anaphase

14. Telophase Separation of chromosomes completed Nucleus reform
2 nucleus and 1 cytoplasm

15. Telophase

16. Cytokinesis Forms two, identical daughter cells
After Mitosis (division of nucleus)
Forms two, identical daughter cells
