1. PTT 23FEB2016
What are the 2 ways that humans can change the traits in plants (or animals)?
For your planners:
OAJ #19
STUDY for Cell Biology Quiz Friday

2. Learning goals for 23FEB2016 I can list the cell phases
I can define mitosis
I can model the stages of mitosis

3. The Cell Cycle & Cell Division

4. The Cell Cycle

5. Animated Cycle

6. MITOSIS

7. Mitosis
The process of cell division which results in the production of two daughter cells from a single parent cell.
The daughter cells are identical to one another and to the original parent cell.

8. Mitosis can be divided into stages
Interphase
Prophase
Metaphase
Anaphase
Telophase & Cytokinesis

9. Interphase The cell prepares for division
Animal Cell
DNA replicated
Organelles replicated
Cell increases in size
Plant Cell
DNA replicated
Organelles replicated
Cell increases in size

10. Interphase Plant Cell Animal Cell
Photographs from:

11. Prophase The cell prepares for nuclear division
Plant cell
Packages DNA into chromosomes
Animal Cell
Packages DNA into chromosomes

12. Prophase Plant Cell Animal Cell
Photographs from:

13. Metaphase The cell prepares chromosomes for division
Animal Cell
Chromosomes line up at the center of the cell
Spindle fibers attach from daughter cells to chromosomes at the centromere
Plant Cell
Chromosomes line up at the center of the cell
Spindle fibers attach from daughter cells to chromosomes at the centromere

14. Metaphase Plant Cell Animal Cell
Photographs from:

15. Anaphase The chromosomes divide
Animal Cell
Spindle fibers pull chromosomes apart
½ of each chromosome (called chromotid) moves to each daughter cell
Plant Cell
Spindle fibers pull chromosomes apart
½ of each chromosome (called chromotid) moves to each daughter cell

16. Anaphase Plant Cell Animal Cell
Photographs from:

17. Telophase The cytoplasm divides
Plant Cell
DNA spreads out
2 nuclei form
New cell wall forms between to nuclei to form the 2 new daughter cells
Animal Cell
DNA spreads out
2 nuclei form
Cell membrane pinches in to form the 2 new daughter cells

18. Telophase Plant Cell Animal Cell
