3. 5.01 Determine and graph the population growth rate of cells
Activity 5-1A page 138

4. 5.02 Illustrate and describe the basic processes of cell division.
Outcome covered in and

5. Define mitosis
The process in which the contents of a cell’s nucleus divide.
Results in two daughter cells identical to the parent.

6. 5.02.2 State and briefly describe the four phases of mitosis
Prophase
Metaphase
Anaphase
Telophase

7. 1. Prophase
The double stranded chromosomes shorten and thicken.
The nuclear membrane begins to fade.

8. 2. Metaphase
X-shaped chromosomes are pulled into a single line across the middle of the cell.

9. 3. Anaphase
The chromatids are pulled to opposite poles of the cell.

10. 4. Telophase
The nuclear membrane forms around each set of chromosomes.
The cell is ready to divide into two separate cells.

11. Four phases of mitosis are followed by cytokinesis

18. 5.2 Asexual Reproduction
Pages

19. 5.04 Distinguish between sexual and asexual reproduction
Only one parent is involved.
Offspring are identical to the parent.
Most reproduce quickly and in large numbers.

20. 5.04.1 Explain methods of asexual reproduction using examples
Binary fission
Fragmentation
Budding
Vegetative Reproduction
Spore Formation

21. 1. Binary Fission
A single parent cell replicates its genetic material and divides into two equal parts.
Amoeba 

22. Bacteria

23. 2. Budding
Part of the cell pushes outward to form an outgrowth or bud.
The bud pinches off to form the new offspring identical to parent.
Not all buds break away.
yeast

24. SPONGE

25. HYDRA

26. 3. Fragmentation When an organism breaks apart as a
result of injury, each fragment then
develops into a clone of its parent.

27. Sea star

28. Japanese Knotweed

29. 4. Vegetative Reproduction
Occurs when special cells, in
plants and roots, divide repeatedly
to form structures that will
eventually develop into plants
identical to the parent.

30. Runners

31. Bulbs

33. 5. Spore Formation
A spore is a reproductive cell that grows into a new individual by mitosis.
Light in weight.
Rely on water, or wind to carry spores away from parent plant.

39. 5.08 Summary of comparison for asexual and sexual reproduction
Advantages Large # of offspring are produced quickly.
Advantages Large colonies can form to out compete.

40. Continued…
Advantages Large # of offspring mean the species may survive when conditions change
Advantages Energy is not required to find a mate.

41. Continued… Disadvantages Offspring are genetic clones.
Negative mutations can destroy large #s.
Disadvantages Those produced close together must compete.

42. Continued…
Disadvantages Unfavorable conditions can wipe out entire colonies.
