| Question | Answer |
|---|---|
| mitosis | cell division of body/somatic cells; used for growth, repair, and reproduction |
| cell cycle | life of a cell |
| interphase | period of growth, cell activity, and DNA replication in the cell cycle. "In-between phase" |
| prophase (order) | 1st and longest phase of mitosis; "prep" phase |
| prophase (description) | phase of mitosis where centrioles move to opposite poles, spindle fibers appear, nucleus disappears, and chromosomes are visible |
| metaphase (order) | 2nd phase of mitosis |
| metaphase (description) | sister chromatids line up in the "middle" of the cell |
| anaphase (order) | 3rd phase of mitosis |
| anaphase (description) | sister chromatids pulled "apart" or "away" |
| telophase (order) | 4th phase of mitosis; "The End" |
| telophase (description) | chromosomes reach opposite poles, new nucleus forms around each set of chromosomes |
| cytokinesis | splitting of the cell's cytoplasm into 2 new cells |
| centromere | "glue" that holds sister chromatids together |
| centriole | "stars" at the opposite ends of the cell. anchors spindle fibers. |
| sister chromatids | copied chromosomes |
| chromosome | visible and condensed structures made up of DNA; passed on to offspring. Long single strand. |
| gene | segment of DNA that codes for a trait |
| chromatin | form of chromosomes during interphase; long tangled strands |
| cancer | malignant growth of cells caused by uncontrolled cell division |
| malignant tumor | harmful, cancerous growth of cells |
| asexual reproduction | production of offspring from one cell of one parent; offspring are identical to parent; no egg and sperm involved |
| budding | asexual reproduction where offspring grow on or off of the parent; yeast |
| binary fission | asexual reproduction in bacteria where the cell splits into two cells |
| vegetative reproduction | asexual reproduction in plants where offspring are produced without seeds or spores. |
| spindle fibers | "ropes" or strands used to move and pull chromatids apart during mitosis |
| Parent cell | Original cell that copies |
| Daughter cell | Cell copied from parent cell |
| Cell division | Division of the cell |
