Distinguish between sexual and asexual reproduction. Take out a piece of paper and write for two minutes what makes you unique . . Human. Cat. Shrimp. Bean. Before Meiosis. Chromosome. number (haploid or diploid?. 46. ?. ?. ?. Number of pairs of homologous. Alleles segregate during meiosis allowing new combinations to be formed by the fusion of gametes. . Understandings:. One diploid nucleus divides by meiosis to produce four haploid nuclei. . The halving of the chromosome number allows a sexual life cycle with fusion of gametes. . How do species become varied?. Do animals and plants reproduce the same ways?. Are there other ways that a species can be varied?. Asexual and Sexual Reproduction. Reproduction produces new individual species. The way a species reproduces determines how much variation the new individual will have. . “The Revelation”. Debrief. ATOTC . essays . For next class….

Ch. 10: Section 1 . Limits to Cell Growth/Size. DNA “Overload” – If a cell grows too large, its DNA could no longer serve the needs of the entire cell. Exchanging materials – if a cell is too large, is struggles to move enough nutrients & wastes throughout the cell and to the cell membrane.
