Across 5. the openings in the envelope that all materials to enter and leave the nucleus 7. which type of fermentation do yeasts use to make bread rise 9. what do all living things need to survive 11. the first step of cellular respiration 14. saclike structure that stores food, water, or wastes 16. very small, lack membranes, makes proteins 18. found in animal cells, needed for cell division 19. type of vesicle that contains enzymes to break down pieces of the cell 20. long, tail-like appendage, helps move the cell 25. found in all cells, protects the cells 27. releases energy from ATP, powerhouse of the cell 33. the process that converts energy in food into ATP 34. madeo of proteins, gives the cell shape 36. organisms that have cells that have a nucleus and membrane bound organelles 37. the cell membrane is made of proteins and this other molecule 38. examples of this macromolecule are DNA and RNA 41. the building blocks of proteins 44. he looked at animal cells 45. directs the cell's activities, contains DNA 46. the compound that stores the energy in our cells 47. these organisms use fermentation to produce cheese, yogurt, and sour cream 48. contains ribosomes, job is to make proteins

Down 1. he was first to name cells 2. he said cells come from preexisting cells 3. what part of the plant absorbs the water needed for photosynthesis 4. job is to make lipids and remove harmful substances 6. the building blocks of lipids 8. short, hairlike, move the cells or the molecules to the cell 10. the sugar that is broken down during glycolysis 12. surrounds the nucleus, contains pores 13. examples of this macromolecule are amylase and keratin 15. organisms that have cells that lack a nucleus 17. the gas produced during photosynthesis that goews into the atmosphere for us to breath 21. cellular respiration produces water and what gas as waste products 22. found in plants and some protists, uses light energy to make sugars 23. substance that does the dissolving of substances in the cell and in the body 24. when our body runs out of oxygen and we can't do CR, we can do this process to produce small amounts of ATP 26. he looked at plant cells 28. the pigment found in leaves that absorbs the sunlight for photosynthesis 29. prepares the proteins for specific jobs and packages proteins into vesicles 30. found inside the nucleus, job is to make ribosomes 31. the building blocks of nucleic acids 32. the DNA in the nucleus is organized into these structures 33. examples of this macromolecule are sugars and starches 35. examples of this macromolecule are cholesterol and Vitamin A 39. made mostly of water, holds all the organelles and cytoskeleton 40. found in plants, outside the cell membrane 42. the building blocks of carbohydrates 43. which cells in our body use lactic acid fermentation when we run out of oxygen
