Question

station 4:

• directions: indicate whether each statement occurs in mitosis, meiosis, or both stages. write the number of the box below in the correct space on your sheet.

1. creates 2 identical cells
2. goes through a stage called metaphase
3. creates 4 unique cells
4. occurs in plants and animals
5. creates a human cell with 23 chromosomes
6. creates a human cell with 46 chromosomes
7. diploid cells are created
8. haploid cells are created
9. contributes to genetic diversity in organisms

Explanation:

1. Mitosis produces 2 genetically identical daughter cells from one parent cell.
2. Both mitosis and meiosis have a metaphase stage, where chromosomes align at the cell's equator.
3. Meiosis produces 4 genetically unique haploid cells through two rounds of division.
4. Both mitosis (for growth/repair) and meiosis (for gamete production) occur in plants and animals.
5. Human meiosis creates gametes (sperm/egg) with 23 chromosomes, the haploid number.
6. Human mitosis creates somatic cells with 46 chromosomes, the diploid number matching the parent cell.
7. Mitosis generates diploid cells that have the full set of chromosomes matching the parent.
8. Meiosis generates haploid cells that have half the chromosome number of the parent.
9. Meiosis creates genetically unique cells via crossing over and independent assortment, driving genetic diversity.

Answer:

• Mitosis: 1, 6, 7
• Meiosis: 3, 5, 8, 9
• Both: 2, 4
