Mitosis & Meiosis:
19. Why do cells need to produce new cells?
20. What is the result of mitosis?
21. The process that produces sex cells is called _______________.
22. What cells are produced during asexual cell reproduction?
23. How are sex cells different from other human cells?
24. How many cells are produced during meiosis? Why?
25. What are homologous chromosomes?
26. ________ ____________ is the life cycle of a cell.
27. What is the difference between sexual and asexual reproduction? (Hint: # of parents)
28. Fill out chart:
Stage of Mitosis
Description
DNA copies; Centrioles copy
Chromosomes condense into chromatids;
nuclear membrane breaks apart
Chromatids line up in the center of the cell
and attach to the spindle fibers
Chromatids are pulled apart to opposite
ends of the cell
Two new nuclei form around
chromosomes; chromosomes unwind
Cytoplasm divides; two new cells are
produced
Drawing of each stage

How Animals Obtain Oxygen
32. Name three ways Animals can obtain oxygen and give an example of an animal or type of animal that
obtains oxygen that way.
