| 2997243149 | Cell Division | The reproduction of cells | 0 | |
| 2997275576 | Cell Cycle | The life of a cell from the time it is first formed during division of a parent cell until its own division into two daughter cells | 1 | |
| 2997285459 | Gametes | Sperm and eggs. Sex cells | 2 | |
| 2997291384 | Genome | Endowment of DNA. Genetic info | 3 | |
| 2997310522 | Chromosomes | Structures that contain DNA | 4 | |
| 2997474407 | Chromatin | The entire complex of DNA and proteins that is the building material of chromosomes | 5 | |
| 2997904635 | Somatic Cells | All body cells except for the sex cells | 6 | |
| 2998275771 | Sister Chromosomes | Duplicated Chromosome | 7 | |
| 2998324842 | Centromere | Area on sister chromosomes where the two chromosomes are attached. | 8 | |
| 2999721405 | Arm | Part of the chromosome that is to the side of centromere | 9 | |
| 2999904373 | Mitosis | The division of the genetic material in the nucleus | 10 | |
| 2999904640 | Cytokinesis | The division of the cytoplasm Cleavage furrow | 11 | |
| 2999928790 | Interphase | Phase in the middle. Consists of G1, S, G2 | 12 | |
| 2999929227 | G1 S G2 | Growth 1: Cell grows (gap 1) Synthesis: Organelles are made Growth 2: Cell grows (gap 2) | 13 | |
| 3102344199 | Five stages of Mitosis | Prophase Prometaphase Metaphase Anaphase Telophase | 14 | |
| 3102461713 | G2 Interphase | Nuclear Membrane still exists 1 or more nucleoli (singular nucleolus) 2 Centrosomes formed by duplication of 1 Each centrosome contains two centrioles | 15 | |
| 3102506642 | Prophase | Chromatin fibers condense and take the shape of chromosomes Nucleoli disappear Duplicated Chromosomes are bound and are called Sister Chromatids Mitotic Spindle begins to form (composed of the centrosomes and the microtubules that extend from them) Star looking thingys at the end called Asters. | 16 | |
| 3102528627 | Prometaphase | Nuclear Envelope fragments Chromosomes become even more condensed Each of the two chromatids of each chromosome now has a kinetochore, a specialized protein structure at the centromere Some of the microtubules attach to the kinetochores, becoming "kinetochore microtubules," which jerk the chromosomes back and forth Nonkinetochore microtubules interact with those from the opposite pole of the spindle. | 17 | |
| 3102546569 | Metaphase | Centrosomes are at opposite parts of the cell Centrosomes line up at Metaphase plate For each chromosome, the kinetochores of the sister chromatids are attached to kinetochore microtubules coming from opposite poles. | 18 | |
| 3102548954 | Metaphase plate | Plane that is equidistant from the centrioles during metaphase. | 19 | |
| 3102558056 | Anaphase | Shortest Phase Cohesion protein cleaved, Centromere no more exist Kinetochore microtubules pull the centrosomes apart towards opposite ends of the cell Cell elongates as chromosomes move to opposite exams By the end of anaphase, both ends contain 1 complete set of chromosomes | 20 | |
| 3102570256 | Telophase | Nuclei form Nuclear envelopes start to appear Spindle Microtubules depolymerize Essentially the ends with a subsection of cytokinesis. | 21 | |
| 3102637488 | Cleavage furrow | Pinch in cytoplasm | 22 |
