Across 2. The tubular passageways that help transport proteins. 4. The jelly-like fluid found inside the cell membrane. 7. a process of cell division htat forms two new new nuclei, each of which has the same number of chromosomes. 9. A nuclear membrane forms around the chromosomes in each cell in this step of mitosis. 10. Two new daughter cells are formed in this stage of cellular reproduction. 13. Known as the clean up crew for cells; helps digest food and broken down cell organelles; most common in animal cells. 17. The movement of certain molecules across the cell membrane that does require energy. 19. The movement of molecules across the cell membrane 20. The chromosomes are pulled apart and move toward opposite ends of the cell in this step of mitosis. 21. The powerhouse of the cell; it makes the energy for the cell by breaking down food molecules for glucose. 23. Two types of this can occur: 1) aerobic- requires oxygen to release the energy stored in food. 2) anaerobic- energy is released without oxygen ( also called fermentation ). 24. The movement of water throughout the cell. 26. When large molecules are surrounded by the cell membrane ( vesicle ) and brought inside the cell. 27. All of the chemical reactions in a cell; this is the process changing energy from one form to another. 28. The chromosomes line up in the middle of the cell in this step of mitosis.

Down 1. This is a group of cells that work together to perform a specific job. 2. When large molecules are carried out of the cell. 3. The movement of certain molecules across the cell membrane that does not require energy. 5. The smallest unit of life. 6. The brain or boss of the cell; it controls all cell functions. 8. The organelle that gives plant cells there green appearance. 11. The water filled sacs that store food, waste, or water for cells; found most commonly in plant cells. 12. The chromosomes start to duplicat themselves and the cell prepares to divide. 14. The nuclear membrane dissolves in this step of mitosis. 15. A group of organs working together to perform a particular function is called this. 16. Anything that can perform life processes by itself is this. 18. The small organelle found in the nucleus that makes ribosomes. 22. Strutures found inside the nucleus that contains all of the hereditary material. 25. A structure that is made up of two or more tissues working together to perform a specicfic function is called this.
