1. On figure 12.1, draw a line connecting the two identical chromatids in cell B and write "sister chromatids" beside it.
2. Each cell "C" would be represented by P/2 DNA.
3. Draw a line to the central constriction point (centromere) of the chromosome in cell A and each chromosome in cells C.
4. Reproduction, growth, renewal and repair are all reasons for cell division in multicellular organisms.
5. In binary fission, the bacterial chromosomes stay attached to the plasma membrane.
6. From a single parent cell, two daughter cells are produced in mitosis.
7. Liver cells, bone cells, nerve cells, muscle cells are called somatic cells. Sperm cells and egg cells are called gametes.
8. In animals, somatic cells have two set(s) of chromosomes.
9. Division of the nucleus is called karyokinesis. Division of the cytoplasm is called cytokinesis.
10. Golgi apparatus, RER, SER, lysosomes, ribosomes all duplicate during the G1 phase of interphase.
11. DNA replication occurs during the S phase of interphase.
Parent Tip: Review the logic above to help your child master the concept of cellular division worksheet.
