Across 1. A structure found inside the nucleus that produces ribosomes. 4. Produces new sex cells with half the chromosomes. 8. "Protein Factory" Where proteins are made. More of this than any other organelle. Smallest of all organelles. Not covered with membrane. 10. When large molecules are carried out of the cell. 12. Two new daughter celles are formed. 13. Made up of cells that are similar in structure and function and which work together to preform a specific activity. 14. All of the chemical reactions that occur in the cell. 16. The chromosomes are pulled apart and move toward opposite ends of the cell. 17. "Brain" Control center of the cell. Controls ALL cellular activities. 18. The movement of certain molecules across the cell membrane that does require energy. 24. "Fort" Supports and protects the cell 29. There are two types of this, aerobic and anaerobic. 30. "ER" Tubular passageways that help transport proteins. Rough ER is usually found near the nucleus. 32. "Clean Up Crew" Helps digest food molecules, waste, cell parts and foreign invaders.

Down 2. When large molecules are surrounded by the cell membrane and brought into the cell. 3. The nuclear membrane disappears. 4. "Power House" Breaks down glucose to provide energy for the cell. Has two membranes. This can divide within the cell. 5. Entire living things that can carry out all basic life processes. 6. The movement of molecules across the cell membrane. Molecules move from areas of higher concentration to areas of lower concentration. (Passive Transport) 7. The movement of water across the cell membrane. Water molecules move from areas of higher concentration to areas of lower concentration to help keep the cell from drying out. (Passive Transport) 9. Made up of tissues that work together to preform a specific activity. 11. Produces new body cells. 12. This has three phases: Interphase, Mitosis, and Cytokinesis. 15. Energy is released without oxygen(also called fermentation) 19. A nuclear membrane forms around the chromosomes in each cell. 20. The chromosomes duplicate and the cell prepares to divide. 21. "Security Guard" Helps control what goes in and out of the cell.(Selectively Permeable) Two layers of phopholipids. 22. "Storage Tank" Water filled sacs found mostly in plants. Stores food, water or waste. 23. Groups of two or more tissues that work together to preform a specific function for the organism. The humans body has 11 of these. 24. Structures found inside the nucleus that contain all of the hereditary material. 25. "Soler Panels" Found only in plant cells. Contains green pigments called chlorophyll (used for photosynthesis) 26. The chromosomes line up in the middle of the cell. 27. "Cell Guts" The jelly-like fluid inside the cell. Holds and supports the organelles. 28. Requires oxygen to release the energy stored in food. 31. These are the basic unit of structure and function in living things.
