VOCABULARY WORDS: Chromatin: Chromosome: Centromere: Sister Chromatids: Spindle Fibers (Microtubules): Centrioles: Homologous Chromosomes: Tetrad: Crossing Over: Somatic Cell: Gamete: Fertilization: Zygote: Binary Fission: Choose Mitosis (Mi), Meiosis (Me), Neither, or Both for the each of the following statements: ______________________- makes sperm and egg cells ______________________- 4 new cells formed ______________________- matching pairs of sister chromatids move to opposite ends of the cell. ______________________-2 new cells formed ______________________- chromosomes attach to spindle fibers ______________________- cells go from being diploid to haploid. ______________________- cells go from being diploid to diploid. _____________________- each new cell has half the number of chromosomes as the parent. _____________________- tetrads are visible. _____________________- each new cell has equal number of chromosomes as the parent. _____________________- function is for growth and replacement of cells. _____________________- function is for sexual reproduction and promotes variation. _____________________- produces eight cells. _____________________- DNA is replicated prior to the process. As a cell gets larger, does its S.A. to Volume ration get larger, smaller, or stay the same? _________________________ Why are cells small?
