Terms | Definitions |
|---|---|
 cell division | the process in reproduction and growth by which a cell divides to form daughter cells |
| asexual reproduction | a reproductive process that involves only one parent and produces offspring that are identical to the parent |
| sexual reproduction | process in which genetic material from two parents combines and produces offspring that differ genetically from either parent |
| chromosomes | threadlike structures made of DNA molecules that contain the genes |
| chromatin | combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus of a eukaryotic cell |
| cell cycle | series of events that cells go through as they grow and divide |
| interphase | cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases |
| mitosis | the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets |
| cytokinesis | organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells |
| prophase | first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus |
| centromere | a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape |
| chromatid | one of two identical strands into which a chromosome splits during mitosis |
| centriole | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope |
| metaphase | second phase of mitosis, during which the chromosomes line up across the center of the cell |
| anaphase | the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle |
| telophase | the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle |
| cyclin | one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells |
| growth factor | a protein that is involved in cell differentiation and growth |
| apoptosis | programmed cell death |
| cancer | any malignant growth or tumor caused by abnormal and uncontrolled cell division |
| tumor | an abnormal new mass of tissue that serves no purpose |
| embryo | the developing human organism from about 2 weeks after fertilization through the second month |
| differentiation | process in which cells become specialized in structure and function |
| totipotent | having the ability to give rise to unlike cells |
| blastocyst | stage of early development in mammals that consists of a hollow ball of cells |
| pluripotent | Stem cells with the potential to differentiate into most any type of cell |
| stem cell | an undifferentiated cell whose daughter cells may differentiate into other cell types (such as blood cells) |
| multipotent | Adult stem cells that can differentiate into a limited variety of cell types. |
