Across 5. a change in an organism's environment that affects the activity of the organism 7. controls the movement of materials into and out of the nucleus through tiny holes 9. nucleus stores 11. ribosomes synthesized 12. which cell is bigger 15. surrounds the nucleus and keeps it separated from the cytoplasm 17. the molecule that all living things have; provides instructions for making proteins 23. this is the process where takes place in the chloroplast 24. is a network of protein filaments that helps the cell to maintain its shape 25. what does "eu" mean 26. organelles break down 27. all living things are made of 28. an organism composed of many cells. 33. thin structure that surrounds a cell ; protects the inside of a cell 34. which cell type has a nucleus and organelles 36. release energy from stored food molecules 39. type of protist which contains chloroplasts and moves 41. is NOT coated with ribosome 44. produce proteins 45. a tissue that acts like a covering 46. forms when part of the cell membrane surrounds an object and pinches off 47. threadlike structures containing the genetic information that is passed from one generation of cells to the next 48. a type of tissue that is important for movement 49. specialized structures that perform important cellular activities ; like "little organs"

Down 1. hair like structures extend from the cells surface 2. components of the cell membrane are assembled 3. packages proteins and materials for distribution to other parts of the cell 4. all the chemical reactions that occour in the cell 6. gel-like substance that is constantly moving 8. requires energy to move into cells 10. lysosome is filled with 13. a tissue that holds things together 14. granular material visible within the nucleus 15. inside the nucleus ; is responsible for assembly/production of proteins within the cell 16. found only in plant cells ; use the energy from sunlight to make energy rich food molecules in a process known as photosynthesis 18. do not have organized organelles 19. the maintanence of a stable internal environment 20. are hollow tubes of protein about 25 nanometers in diameter that serve as tracks 21. long , thin fibers that function in the movement and supports the cell 22. an organism composed of only one cell 29. what does "pro" mean 30. a widely accepted explanation of the relationship between cells and living things 31. organelles break down food to make 32. breakdown lipids , carbohydrates , and proteins from food into particles that can be used by the rest of the cell 35. found only in plants ; provides support and protection for the cell 37. which cell is smaller 38. storage of liquids ; to create pressure in order to create there structure 40. control center of the cell ; DNA 42. is coated with ribosome 43. a special type of diffusion which refers only to the movement of water across the cell membrane , it requires energy
