1. Cellular Reproduction

2. - EXACTLY THE SAME NUMBER
PURPOSE OF MITOSIS:
TO PRODUCE TWO NEW NUCLEII WITH…
EXACTLY THE SAME KIND
and
- EXACTLY THE SAME NUMBER
. . . OF CHROMOSOMES
AS THE PARENT CELL.

3. Eukaryote Complex Have nucleus and many organelles
Plants, animals, fungi, protista

4. Prokaryote Simple Lacking many organelles No nucleus
Plasimid DNA ring – Bacteria

5. Definitions Mitosis:Process of cell division
Chromosome:structure of DNA, where genes are located
Diploid: Containing a complete set of chromosomes
Haploid: Containing half a set of chromosomes (gamete)

6. Definitions
Meiosis: Process of cell division by which gametes are formed.
Gamete: Reproductive cell, containing haploid set of chromosomes (1/2 set)
Zygote: Two gametes joined together, or a fertilized egg cell

8. The Cell Cycle (3 parts)
1. Interphase: Time when all parts of cell including DNA replicates (doubles)
2. Mitosis: Process of division, made up of 4 phases.
3. Cytokinesis: Division of the cytoplasm to form two separate cells.

9. INTERPHASE

10. interphase
interphase

11. nucleolus (if any) still visible INTERPHASE:
nuclear envelope
clearly visible
chromatin, NO
chromosomes,
yet

12. Mitosis Prophase: Chromosomes condense and become visible.
Each chromosome has duplicated and now consists of two sister chromatids.
At the end of prophase, the nuclear envelope breaks. 

13. Mitosis Metaphase: The chromosomes align at the equator (middle)
Are held in place by microtubules attached to the mitotic spindle and to part of the centromere.  

14. Mitosis Anaphase: The centromeres divide. Sister chromatids separate
Move toward the corresponding poles.  

15. Mitosis
Telophase:
The condensed chromatin expands and microtubules disappear.
The nuclear envelope reappears.
