Cells and the Cell Cycle

7. structures inside a cell that has specialized functions
10. organisms made up of only one cell
12. sister chromatids are held together by this structure
15. organisms made up of more than one cell
17. the process by which cells become different types of specialized cells
18. the period of time during the cell cycle of a cell's growth and development

1. the organelle that provides ATP energy to the cell
2. groups of tissues working together to perform a particular job
3. the part of a eukaryotic cell that directs cell activities and contains genetic information
4. chromosomes are pulled away by spindle fibers during this phase
5. the cycle of growth, development, and division
6. during this phase spindle fibers begin to disappear
8. unspecialized cells that are able to develop into different cells
9. the type of energy created in cells
11. when the cell and the cytoplasm divides
13. division of the nucleus
14. DNA is copied and the nucleus dissolves during this phase
16. chromosomes line up in the middle of the cell during this phase
17. the molecule that carries genetic information for the development and functioning of an organism
19. groups of cells that work together to carry out a specific function
