Biology Ch. 11 Vocab
Across
- 7. process by which cells become specialized in structure and function
- 13. part of eukaryotic cell division during which the cell nucleus divides
- 16. region of a chromosome in which the two sister chromatids attach
- 17. process in reproduction involving a single parent that result in offspring that are genetically identical to the parent
- 19. developing stage of a multicellular organism
- 22. mass of rapidly dividing cell that can damage surrounding tissue
- 23. type of reproduction in which cells from two parents unite to form the first cell of a new organism
- 25. one of two identical “sister” parts of a duplicated chromosome
- 26. process of programmed cell death
- 27. phase of mitosis in which the chromosomes line up across the center of the cell
Down
- 1. process by which a cell divides into two daughter cells
- 2. cells that are capable of developing into most, but not all, of the body’s cell types
- 3. cell with limited potential to develop into many types of differentiated cells
- 4. factor one of a group that of external regulatory proteins that stimulate the growth and division of cells
- 5. stage of early development in mammals that consists of a hollow ball of cells
- 6. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
- 8. cells that are able to develop into any type of cell found in the body (including the cells that make up the extra-embryonic membranes and placenta)
- 9. one of a family of proteins that regulated the cells cycle in eukaryotic cells
- 10. period of the cell cycle between cell divisions
- 11. structure in an animal cells that helps to organize cell division
- 12. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
- 14. unspecialized cell that can rise to one or more types of specialized cells
- 15. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
- 18. division of the cytoplasm that to form two separate daughter cells
- 20. disorder in which some of the body’s cells lose the ability to control growth
- 21. threadlike structure of DNA and proteins that contain genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes, they are found in the cytoplasm
- 24. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
- 26. phase in mitosis in which the chromosomes separate and move to opposite ends of the cell
