Across 1. most simple of living things 3. the waste material released from a leaf during the process of photosynthesis 7. the loss of water from a leaf 8. these regulate the opening and closing of stomata 11. a virus which invades a bacterial cell 13. the sugar that makes up the cell wall 14. openings on the leaf which allow carbon dioxide to enter the leaf and oxygen to exit the leaf 18. the theory that livng things could arise from non-living matter 19. this refers to the structures that are on the inside of a cell 20. provide the cell with energy and are known as the "Powerhouse" of the cell 21. scientist credited with disproving the theory that living things could come from non-living material 22. has pores and allows certain substances to move in and out of the cell 23. non-living but contains DNA 26. number of pairs of chromosomes in humans 28. the transfer of pollen from the anther to the stigma 32. living 33. an offspring created from a piece of the parent, a bud, or when a cell splits into 2 new cells 36. structure of a nerve cell that functions to send messages throughout the body 38. the process of the sperm and egg unititng 39. sends and receives messages in organisms 42. the struggle among organisms to survive 48. false foot 49. functions to attract pollinators 50. this forms when the pollen grain lands on the stigma and is how the sperm gets to the ovary to fertilize the egg 51. specialized plant tissue which transports water and minerals to the leaf for photosynthesis 52. organelles "float" inside this jelly-like substance 53. type of protist which contains chloroplasts and moves 54. female sex cell 55. the "sticky" structure of the female reproductive organ of a flower which "catches" pollen grains 56. produce the proteins needed by the cell 57. the 2 layers of food-making cells inside a leaf 58. a fertilized egg 59. contains DNA and are how ferns reproduce

Down 2. the organelles function to transport proteins and other materials from one part of the cell to another 4. these make-up the top layer of food-making cells 5. raw materials of photosynthesis 6. organelles which function to receive, package, and send out proteins within the cell 9. the male reproductive organ of a flower 10. stores water and other substances inside the cell 12. protects a bud of a plant 15. structure which allows a euglena and sperm to move 16. type of reproduction involving the uniting of a sperm and egg 17. tiny hair-like structures which line our lungs and noses and also help Paremecia move 22. a waxy layer on the top of a leaf whcih prevents water loss 24. male sex cell 25. holds up the anther 27. the ability of an organism to maintain fairly constant internal conditions, even when the external environment changes 29. how a bacteriaphage attaches to a bacterium 30. sugar produced during photosynthesis 31. a gas needed by a plant to begin photosynthesis 34. cells whose DNA is inside a nucleus 35. absorbs light energy to begin a chemical reaction called photosynthesis 37. contains a larger vacuole, chloroplasts, & cell wall 40. part of a nerve cell which receives messages throughout the body 41. controls all activities of the cell--known as the brain of the cell 43. the female reproductive organ of a flower 44. organelles which contain chemicals that break down food particles and worn out cell parts, these are known as the "clean-up" parts of the cell 45. when 2 or mor
