Across 1. found only in plants ; provides support and protection for the cell 7. granular material visible within the nucleus 10. long , thin fibers that function in the movement and supports the cell 14. what does "pro" mean 15. do not have organized organelles 16. a widely accepted explanation of the relationship between cells and living things 17. all the chemical reactions that occour in the cell 22. specialized structures that perform important cellular activities ; like "little organs" 23. a special type of diffusion which refers only to the movement of water across the cell membrane , it requires energy 25. surrounds the nucleus and keeps it separated from the cytoplasm 26. storage of liquids ; to create pressure in order to create there structure 27. release energy from stored food molecules 31. this is the process where takes place in the chloroplast 34. controls the movement of materials into and out of the nucleus through tiny holes 36. is coated with ribosome 37. packages proteins and materials for distribution to other parts of the cell 38. is NOT coated with ribosome 39. an organism composed of many cells. 40. gel-like substance that is constantly moving 41. which cell is smaller 42. which cell is bigger 44. components of the cell membrane are assembled

Down 1. threadlike structures containing the genetic information that is passed from one generation of cells to the next 2. found only in plant cells ; use the energy from sunlight to make energy rich food molecules in a process known as photosynthesis 3. the maintanence of a stable internal environment 4. an organism composed of only one cell 5. the molecule that all living things have; provides instructions for making proteins 6. is a network of protein filaments that helps the cell to maintain its shape 8. control center of the cell ; DNA 9. organelles break down food to make 11. thin structure that surrounds a cell ; protects the inside of a cell 12. are hollow tubes of protein about 25 nanometers in diameter that serve as tracks 13. what does "eu" mean 18. a change in an organism's environment that affects the activity of the organism 19. forms when part of the cell membrane surrounds an object and pinches off 20. organelles break down 21. produce proteins 24. nucleus stores 28. requires energy to move into cells 29. lysosome is filled with 30. breakdown lipids , carbohydrates , and proteins from food into particles that can be used by the rest of the cell 32. inside the nucleus ; is responsible for assembly/production of proteins within the cell 33. ribosomes synthesized 35. which cell type has a nucleus and organelles 43. all living things are made of
