Document Summary

Product: - mother cell divides to produce 2 daughter cells. Mother cell has 46 chromosomes and both daughter cells have 46 chromosomes. Cytoskeleton microtubules pull cell membrane along the equator. Cell membrane pinches inward to form a cleavage burrow. Cell membrane fuses together when contact is made. Golgi apparatus produces vesicles containing cell wall material. Vesicles move toward cell equator and fuse to each other. Produces a cell plate (cellulose with cell membrane on each side) Cell grows and fuses to existing cell wall & membrane. Product: - mother cell divide into 4 daughter cells. Mother cell has 46 chromosomes and 4 daughter cells have 23 chromosomes. Meiosis ii: prophase ii, new poles, metaphase ii, normal, anaphase ii, telophase ii, normal, cytokinesis ii. Dna replication: normal (sister chromatids pulled to opposite sides, normal, but results in 4 unique haploid gametes. The result is the formation of two new dna molecules from one original.
