Question | Answer |
---|---|
structure in the nucleus which contains hereditary material | Chromosome |
holds together the two chromatid which make a chromosome | Centromere |
single strand of hereditary material; half a chromosome | Chromatid |
attaches to the end of the spindle fibers to move the chromosomes | Centriole |
attaches to the centromere during mitosis to help move the chromosomes | Spindle Fibers |
process in which the nucleus of a cell divides to create two new nuclei; purpose is to create two new cells identical to the original | Mitosis |
chromosomes duplicate; where cells spend most of their life | Interphase |
chromosomes pair up and nuclear membrane dissolves; first step in mitosis | Prophase |
pairs of chromosomes line up in the middle of the cell | Metaphase |
chromosomes split and move to opposite sides of the cell | Anaphase |
new nuclear memberane forms to create two new cells | Telophase |
two cells formed in mitosis separate; a new cell membrane forms | Cytokinesis |
process of cell division which forms four reproductive cells from one original cell | Meiosis |
cell which makes up all of an organism; produced through mitosis | Body cell |
male or female cell used in reproduction; produced through meiosis | Sex/reproductive cell |
a cell which has two of every chromosome; body cell | Diploid cell |
a cell with only half the number of chromosomes all other cells have; reproductive cell | Haploid cell |
the life cycle of a cell | Cell Cycle |
