	Mitosis	Meiosis
Parent cell diploid or haploid
Number of daughter cells	2	4
Daughter cells diploid or haploid
Are homologous chromosomes paired?
Does synapsis form?	no	Synapsis form
Does a daughter cell have the same, ¾ , ½ , or ¼ the amount of DNA as the parent cell?
Type of cell produced (somatic or gamete)

1. Determine if the following stages have one or two sister chromatids moving to the poles.

Anaphase, Anaphase I, and Anaphase II:

2.Give two reasons explaining why skin cells reproduce more quickly than bone cells

3. Describe what happens to adipose cells numbers and size when an individual loses weight.

Answer 1

Answer to the first question:

Comparison of mitosis and meiosis:

Cells in our body divide by two processes, mitosis and meiosis. During mitosis a diploid parent cell is divided into two diploid daughter cells. On the other hand, meiosis involves division of a diploid parent cell into four haploid daughter cells. Mitosis takes place for body growth, whereas meiosis takes place to form gametes (sperm and ovum).

The table can be completed as:

Answer 1:

Anaphase: It takes place during mitosis, and one sister chromatid moves to opposite pole.

Ansphase I : It occurs during meiosis I and two sister chromatids move to the opposite poles.

Anaphase II : This occurs during meiosis II and one sister chromatid moves to the opposite poles.
