directions: identify each statement below as applying to “somatic cells” or “gametes.”

1. another term for sex cells gametes
2. egg and sperm
3. formed throughout an organism’s life
4. form in body cells
5. identical to all of the other cells of similar function
6. cells are haploid

directions: identify the stage of meiosis that is described below.

1. sister chromatids line up in the middle of the cell.
2. four individual nuclear membranes begin to form.
3. sister chromatids are separated
4. the cytoplasm is split and forms two cells.
5. crossing over occurs.
6. paired homologous chromosomes separate.

Explanation:

1. Gametes are sex - cells. Egg and sperm are gametes. Somatic cells are formed throughout an organism's life and in body cells, and are identical to other cells of similar function. Gametes are haploid. In meiosis II, sister chromatids line up in the middle of the cell, sister chromatids are separated, and four individual nuclear membranes begin to form. Cytokinesis (cytoplasm splitting) occurs in both meiosis I and II. Crossing - over and separation of homologous chromosomes occur in meiosis I.

Answer:

1. gametes
2. gametes
3. somatic cells
4. somatic cells
5. somatic cells
6. gametes
7. meiosis II
8. meiosis II
9. meiosis II
10. meiosis I and II
11. meiosis I
12. meiosis I
