A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers. 5. Factor A group of external regulators that stimulate growth, embryonic developement and healing. 6. A state of early development of mamals that consists of an empty ball of cells. 7. The material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed; small, thin strands. 8. A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of DNA. 9. The second stage of cell division during which the chromosomes line up along the equator of the cell, and become attached to the spindle fibers. 10. Capable of giving rise to several different cell types. 12. A swelling or enlargement of a part of the body, generally due to uncontrolled cell growth, whether benign or malignant. 14. The normal process by which a less specialized cell develops or matures to become more distinct in form and function. 17. An unborn or unhatched offspring in the process of development. 21. The chromatids gather at either end of the cell and two new nuclear membranes begin to form. 22. reproduction Production of new living organisms by combining genetic information from two individuals of different types. 1. Cycle The cell cycle, or cell-division cycle, is the series of events that takes place in a cell leading to its division. 2. Each of the two threadlike strands into which a chromosome divides. 3. The point on a chromosome by which it is attached to a spindle fiber during cell division. 4. A type of cell death in which the cell uses specialized cellular signals to kill itself. 7. The cytoplasmic division of a cell at the end of mitosis. 9. Having the ability to differentiate to a limited number of cell types or into a closely related family of cells. 11. The resting phase between successive mitotic divisions of a cell; the cell preformes its specialized function in this phase. 13. Reoroduction Reproduction without the fusion of gametes; reproduction of exact genetic coppies with one parent organism. 15. Capable of giving rise to any cell type. 16. The first stage of cell division, during which the chromosomes become visible as paired chromatids and the nuclear membrane disolves. 18. The dividing of a cell; consists of 5 phases. 19. Cell An undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more types of cells; the first few cells in all mammals. 20. Any of a number of proteins associated with the cycle of cell division that are thought to initiate certain processes of mitosis. 23. The sister chtomstids separate and are pulled apart.
