Term | Definition |

Asexual Reproduction | Reproduction that requires only one parent and produces offspring that are genetic copies of the parent |
Binary Fission | A form of asexual reproduction in which a single parent cell replicates its genetic material and divides into two equal parts |
Budding | A form of asexual reproduction in which areas of an individual may undergo repeated mitosis and cell division and can develop into an identical organism |
Cancer | The result of uncontrolled cell division |
Cell Cycle | The three stages of the life of a cell, which include interphase, mitosis, and cytokinesis |
Clone | An identical genetic copy of an organisms parent |
Cytokinesis | The final stage of the cell cycle, which separates the two nuclei and cell contents into two daughter cells |
Fragmentation | A form of asexual reproduction in which each fragment of an organism develops into a clone of its parent |
Interphase | The first stage of the cell cycle, in which calls carry out life functions and cells that divide prepare for cell division |
Mitosis | The second stage of the cell cycle; the process in which the duplicated contents of the cell's nucleas divides into two equal parts |
Replication | The process during which the cell copies the 3 billion base pairs of DNA information in the nucleas |
Spindle Fibres | Tiny tube-like structures made of protein to which chromosomes attach during cell division |
Spore | Reproductive cells that grow into new individuals by mitosis |
Stem Cell | Cells that have the potential to become many different types of cells; two types of stem cells are embryonic stem cells and adult stem cells |
Vegetative Reproduction | Reproduction in which special cells, usually in plant stems and plant roots, divide repeatedly to form structures that will eventually develop into a plant identical to the parent |
