| Question | Answer |
|---|---|
| The stages of life for a cell | Cell Cycle |
| Cells carry out life functions | Interphase |
| Divides the cell's nucleus into two equal parts | Mitosis |
| Separates two nuclei and cell contents into two daughter cells | Cytokinesis |
| DNA makes an identical copy of itself | Replication |
| Joins sister chromatids together | Centromere |
| Half of a double stranded chromosome | Chromatid |
| Chromosomes become visible; nuclear membrane disappears | Prophase |
| Chromosomes line up along the equator | Metaphase |
| Sister chromatids separate to the poles | Anaphase |
| Nuclear membrane forms around two new nuclei | Telophase |
| Attaches to centrioles and centromere; can contract | Spindle fibers |
| Organize the spindle fibers during prophase | Centrioles |
| Final stage of cell division | Cytokinesis |
| Forms during cytokinesis in plant cells | Cell plate |
| In animal cells, the cell membrane _________ together during cytokinesis | Pinches |
| Uncontrolled cell division | Cancer |
| Collection of undifferentiated cells | Tumour |
| Spreading of cancer cells | Metastasis |
| Identical genetic copy of a parent | Clone |
| One parent required to produce an offspring | Asexual reproduction |
| Single cell organism dividing into two equal parts | Binary fission |
| Growth of tissue of of a parent; genetically identical | Budding |
| Broken off part of an organism may develop into a clone of the parent | Fragmentation |
| Runners, shoots, cuttings, grafting | Vegetative reproduction |
| Reproductive cell that can grow into an organism | Spore formation |
| Have potential to become different cell types | Stem cells |
