SVHS LAB BIOLOGY
Unit 6: CELL REPRODUCTION: MITOSIS & MEIOSIS
Fall 2013
UNIT OUTCOMES:
A) Explain the structure of a chromosome such as those found in the human cell. Contrast sex chromosomes and
autosomes. Contrast a haploid cell and diploid cell in terms of chromosomes. Give examples of each type.
(Pages 151-153)
B) Describe the steps of the cell cycle and explain what important actions take place in each of the stages.
Include the three separate stages of interphase. (Pages 154-155)
C) Describe the four stages of mitosis and explain what happens in each of the stages. Explain how mitosis in
animal and plant cells differs. (Pages 156-157; web activities)
D) Explain where meiosis occurs, what is accomplished regarding chromosome numbers by the process, and why
the process is required if an organism reproduces sexually. (Pages 161-163)
E) Explain how fertilization restores the diploid number of chromosomes in the fertilized egg, the stages that the
early embryo goes through, the three embryonic membranes form, and what organs develop from each cell
layer. (Pages 663-666)
