Across 1. controls the movement of materials into and out of the nucleus through tiny holes 8. nucleus stores 9. all living things are made of 11. long , thin fibers that function in the movement and supports the cell 12. organelles break down 13. this is the process where takes place in the chloroplast 15. breakdown lipids , carbohydrates , and proteins from food into particles that can be used by the rest of the cell 18. an organism composed of only one cell 19. which cell type has a nucleus and organelles 21. packages proteins and materials for distribution to other parts of the cell 22. granular material visible within the nucleus 24. requires energy to move into cells 25. is a network of protein filaments that helps the cell to maintain its shape 27. which cell is smaller 28. is NOT coated with ribosome 31. threadlike structures containing the genetic information that is passed from one generation of cells to the next 34. thin structure that surrounds a cell ; protects the inside of a cell 38. control center of the cell ; DNA 39. found only in plant cells ; use the energy from sunlight to make energy rich food molecules in a process known as photosynthesis 41. a tissue that holds things together 42. do not have organized organelles 43. is coated with ribosome 44. gel-like substance that is constantly moving 47. all the chemical reactions that occour in the cell 48. hair like structures extend from the cells surface 49. produce proteins 50. inside the nucleus ; is responsible for assembly/production of proteins within the cell

Down 2. components of the cell membrane are assembled 3. lysosome is filled with 4. a change in an organism's environment that affects the activity of the organism 5. storage of liquids ; to create pressure in order to create there structure 6. a tissue that acts like a covering 7. sugar produced during photosynthesis 10. particles move from one area where there are a lot of particles, to an area where there are fewer of its own kind. 14. organelles break down food to make 16. surrounds the nucleus and keeps it separated from the cytoplasm 17. an organism composed of many cells. 20. the molecule that all living things have; provides instructions for making proteins 23. release energy from stored food molecules 26. forms when part of the cell membrane surrounds an object and pinches off 29. the maintanence of a stable internal environment 30. a widely accepted explanation of the relationship between cells and living things 32. type of protist which contains chloroplasts and moves 33. what does "eu" mean 35. are hollow tubes of protein about 25 nanometers in diameter that serve as tracks 36. what does "pro" mean 37. which cell is bigger 40. specialized structures that perform important cellular activities ; like "little organs" 41. found only in plants ; provides support and protection for the cell 42. ribosomes synthesized 45. a special type of diffusion which refers only to the movement of water across the cell membrane , it requires energy 46. a type of tissue that is important for movement
