  1. Cell Division Study Guide

  2. Mitosis • Asexual • Cytokinesis • Prophase, Metaphase, Anaphase, Telophase • Somatic, skin, muscle, liver, blood, nerve • 46, somatic cells • Growth, repair, and reproduction • Reduce the number of chromosomes to maintain the species chromosome number after fertilization • Sperm, testes, spermatogenesis • Eggs (ova), ovaries, oogenesis • Asexual

  3. Sexual • Union of the egg and sperm N+N=2N, zygote diploid • Crossing-over, synapsis of prophase 1 • Cleavage furrow, cell plate • 1cell, 2nuclei • Parthenogenesis asexual

  4. Monotreme • Mom, dad • Tumor • 2 daughter cells genetically identical to the parent cell • Crossing over, fertilization, independent assortment • 4 daughter cells, haploid in number, genetically different • Centromere • 4 • 1, 3 • Vegetative propagation, regeneration, binary fission, sporulation, budding

  5. metaphase, telophase, prophase, interphase, anaphase • Marsupial • Placental • Fertilization outside body, fertilization inside body, internal • Sperm, egg, zygote, cleavage, blastula, gastrula • Identical twins • External fertilization • 1, 2 • False • 2, 2 • Identical twins • true

  6. Same length, centromere in same location, and same genes 1.C 2.A 3. X is sporulation 5 B 6 C 7C 8B 9D 10D 11A 12C 13D

  7. 3 • 4 • Baby, A is placenta B is umbilical cord C is uterus D is amniotic fluid A is 1 is 2
