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. |
