1. Topic: Reproduction
Aim: Explain the processes of asexual reproduction and mitosis.
Do Now: Explain how AIDS disrupts homeostasis.
HW: Ditto – Locomotion Review (both sides)

2. Chromosomes
Found in the nucleus
Made of genes  DNA

4. Centromere
Chromatid
Chromatid

5. Centromere
Chromatid
Chromatid

6. Offspring identical to parent Involves MITOSIS
Asexual Reproduction
1 parent
Offspring identical to parent
Involves MITOSIS

7. Mitosis
Cell division
2 daughter cells have same # of chromosomes 50 50 50

9. Interphase
Chromosomes replicate

12. Prophase Nuclear membrane breaks down Spindle fibers form centrioles

14. Metaphase
Chromosomes move to MIDDLE of cell

16. Chromosomes pulled apart Move to opposite poles (AWAY)
Anaphase
Chromosomes pulled apart
Move to opposite poles (AWAY)

19. Nuclear membrane reforms
Telophase
Nuclear membrane reforms
Cytokinesis begins

21. What is cytokinesis? Division of cytoplasm
Animal cells: cell membrane pinches in
What is cytokinesis?

22. Plant cells: cell plate forms to separate cells

23. RESULT = 2 new cells with same # of chromosomes as parent cell.

25. Let’s Review!
Describe where chromosomes are found and what they are made up of.
Describe 2 characteristics of asexual reproduction.
Describe what occurs at each phase of mitosis.

26. Infectious diseases are caused by
deficiencies in the diet
allergies
microscopic organisms that can be transmitted from one organism to another
malfunctioning organs

27. A person with AIDS is likely to develop infectious diseases because the virus that causes AIDS
destroys cancerous cells
damages the immune system
increases the rate of antibody production
increases the rate of microbe destruction

28. In some individuals, the immune system attacks substances that are usually harmless, resulting in
an allergic reaction
a form of cancer
an insulin imbalance
a mutation

29. Uncontrolled cell division is known as
allergies
cancer
AIDS
infectious

30. The type of immunity in which antibodies and memory cells are produced is called
temporary immunity
active immunity
passive immunity
long-term immunity

31. IPMAT REMEMBER! Interphase Prophase Metaphase Anaphase Telophase
IPMAT
A mnemonic to help remember the stages of mitosis.

34. Mitosis – bone cells Interphase/Prophase Parent cell Metaphase
Telophase  2 daughter cells
Anaphase

35. Rat – epithelial cells

38. 1 & 2: interphase
3,4,& 5: prophase
6:metaphase
7 & 8: anaphase
9 & 10: telophase (& cytokinesis)
