Ch 8 - Cell Growth
Ch 8 Cell Growth and Reproduction
| Question | Answer |
|---|---|
| Anaphase | The third phase |
| Apoptosis | programmed cell death |
| Asexual reproduction | reproduction using one parent |
| Autosomes | All the other chromosomes in the organism. |
| Binary Fission | The division of a prokaryotic cell into two offspring cells. |
| Cancer | any malignant growth or tumor caused by abnormal and uncontrolled cell division |
| Cell cycle | series of events that cells go through as they grow and divide |
| Cell division | the process in reproduction and growth by which a cell divides to form daughter cells |
| Cell Plate | In a plant cell |
| Centriole | Cell organelle that aids in cell division in animal cells only |
| centromere | The point where two Chromatids are attached. |
| Chromatid | each half of the chromosomes |
| chromatin | Less tightly coiled DNA-protein complex. |
| chromosomes | Rod-shaped structures made of DNA and Protein. |
| Crossing over | Chromotids may break off and connect to adjacent Homologous Chromosomes. |
| Cyclin | one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells |
| Cytokinesis | the division of the cell's cytoplasm |
| Diploid | the set of two chromosomes. |
| Gametes | haploid reproduction cells. |
| Genetic Recombination | when a new mixture of genetic material is created. |
| Growth factor | one of a group of external regulatory proteins that stimulate the growth and division of cells |
| Haploid | one of the chromosomes in the diploid |
| Histones | Maintain the shape of chromosomes and aid in the tight packing of DNA. |
| Homologous Chromosomes | the copy of each autosomes |
| Independent Assortment | The random seperation of the Homologous Chromosomes. |
| Interphase | the time between cell division |
| Karyotype | A photomicrograph of the chromosomes in a normal dividing cell found in a human. |
| Meiosis | Reduces the chromosome count by half in new cells. |
| Metaphase | The second phase of Mitosis |
| Mitosis | Cell division that results in new cells. |
| Oogenesis | the production of mature eggs. |
| Polar body | The other three products of meiosis that eventually degenerate. |
| Prophase | the first phase of mitosis |
| Sex chromosomes | determine the sex of the chromosomes |
| Sexual reproduction | The production of offspring through meiosis and the union of a sperm and an egg cell. |
| Spermatogensis | the production of sperm cells. |
| Spindle Fibers | Radiate from the newly seperated centromeres to prepare for Metaphase. |
| Synapsis | The pairing of Homologous Chromosomes. |
| Telophase | After the chromosome seperates |
| Tetrad | Each pair of Homologous Chromosomes. |
| Tumor | A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably. |
