Chapter 12 The Cell Cycle Review
  1. The continuity of life is based upon cell , the reproduction of cells.
     
     
     
     
  2. Prokaryotes reproduce by a type of cell division called fission.
     
     
     
     
  3. Eukaryotic DNA is packaged into that condenses into during cell division.
     
     
     
     
  4. Somatic cells reproduce by , while gametes reproduce by .
     
     
     
     
  5. Mitosis is preceded by an ; together these constitute the cell .
     
     
     
     
  6. The mitotic phase consists of , the division of the nucleus, and , the division of the cytoplasm.

Chapter 13 Meiosis and Sexual Life Cycles Review
  1. In reproduction, one parent produces genetically offspring by fission or by .
     
     
     
     
  2. In reproduction, two parents produce offspring that have unique combinations of inherited from each parent.
     
     
     
     
  3. A is an ordered, visual representation of the in a cell.
     
     
     
     
  4. Each chromosome consists of two identical sister , attached to the .
     
     
     
     
  5. are sex cells that are produced from cells in organs called by meiosis.
     
     
     
     
  6. occurs when a sperm fuses with an ovum, forming a diploid , which grows and develops into an adult organism.
     
     
     
     
    Review: Asexual and Sexual Life Cycles
     
     
     
     
  7. Since meiosis reduces the number of chromosome sets from to , two cellular divisions are required, preceded by a single .
     
     
     
     
    • Meiosis is the chromosome division.
       
       
       
       
    • Meiosis II then produces haploid daughter cells.
     
     
     
     
    Summary: difference between mitosus and meiosis.
     
     
     
     
  8. Sexual reproduction produces genetic by several mechanisms: independent , crossing , and random fertilization.
     
     
     
     
    Review: Genetic Variation
     
     
     
     
  9. The tremendous genetic variation made possible by meiosis and reproduction provides raw material for evolution by selection.
