| Question | Answer |
|---|---|
| Two types of cell division | Mitosis Meiosis |
| Mitosis | Cell division of somatic cells that produces two daughter cells with identical genetic information, 46 chromosomes |
| Meiosis | Cell division that gives rise to sex cells, produces cells with half the number |
| Chromatin | Becomes a chromasome |
| Chromosomes | Tightly coiled rods of chromatin |
| Chromatid | Each chromosome contains two |
| Centromere | The attachment point of chromatids |
| Centrioles | Divide and move to opposite sides of the cell |
| spindle fibers | Microtubules projecting from Centrioles that chromosomes attach |
| Interphase | Cell growth, genetic material duplication |
| Phases of interphase | G1 S G2 |
| Prophase | Begins cell division |
| Metaphase | Duplicated chromosomes move to middle |
| Anaphase | Chromosomes are pulled apart by microtubules |
| Telophase | Chromosomes elongate and form chromosome threads |
| Cytokinesis | Two new cells are formed |
| Cell division is controlled by | The DNA of the cell External controls like hormone and growth factors |
| Cans begins at the ______ level | Cellular |
| Tumor | Abnormal growth of cells |
| Benign tumors | Remains in place |
| Malignant tumors | Cencerous |
