Cell Growth and Division
| Question | Answer |
|---|---|
| Cell Division | The process by which a cell divides into new daughter cells |
| Asexual Reproduction | The production of genetically identical offspring from a single parent cell. No sharing of DNA. |
| Sexual Reproduction | The production of genetically unique offspring through the fusion of parent cells and sharing of DNA. |
| Chromosomes | Threadlike structure of DNA and proteins that contains genetic information |
| Chromatin | DNA tightly coiled around histones |
| Cell Cycle | Series of events in which the cell grows, prepares for division, and divides to form two daughter cells |
| Interphase | Period of cell cycle between mitotic divisions |
| Mitosis | Division of a Eukaryotic cell's nucleus |
| Cytokinesis | Division of the cytoplasm to form two separate daughter cells |
| Centromere | Region of a chromosome where sister chromatids attach |
| Chromatid | One of two identical "sister" parts of a duplicated chromosome |
| Centriole | Structure in an animal cell that helps to organize cell division |
| Cyclin | One of a family of proteins that regulates the cell cycle in eukaryotes |
| Growth Factor | One of a group of external regulatory proteins that stimulates growth and division of cells |
| Apoptosis | Process of programmed cell death |
| Cancer | Disorder in which some of a body's cells lose the ability to control growth |
| Tumor | A mass of cells |
| Embryo | Developing stage of a multicellular organism |
| Differentiation | Process in which cells become specialized |
| Totipotent | Cells that are able to develop into any type of cell in the body |
| Blastocyst | Stage in the early development of mammals that consists of a hollow ball of cells |
| Pluripotent | Cells that are able to develop into most, but not all cell types of the body |
| Multipotent | Cells with limited potential to develop into differentiated cells |
