8. Single celled pond organisms, plants
9. – Metabolic process
- Increase protein production
- Increase organelles
- Grow in size
- Replicate DNA (S phase)
10. Mitosis and cytokinesis
13. sex chromosomes…brother has 1 X and 1 Y
chromosome/Sister has 2 X chromosomes
14. When two haploid cells fertilize, then form a
diploid cell that grows into an adult by Mitosis.
15. tetrad consists of 1 pair of homologous
chromosomes (4 sister chromatids). Tetrads form
during prophase I of meiosis.
16. both involve separation of sister chromatids. In
Meiosis…haploid number is reached. In Mitosis, the
cell stays diploid.
17. Crossing over and independent assortment.
19. a- plant cell because cell plate forming; b- cell
wall, cell plate and nucleus
20. a- asexual; b- Mitosis in all; c- new plants are
genetically identical
24. a- duplication of chromosomes occurs in
Interphase; b- gametes only contain half the number
of chromosomes; c- cells spend most of their time in
Interphase.
