Across
  1. 3. a chemical process in which oxygen is used
  2. 4. Allows light to settle onto slide
  3. 12. The chemical process in which stored energy is broken down so it can be used by an organism to survive when there is no food source available.
  4. 14. adenosine triphosphate, a molecule that provides energy for cellular respiration
  5. 16. a process by which glucose is partially broken down into pyruvic acid without the use of oxygen
  6. 17. a small structure that can store food (leucoplast) or pigment (chromoplast).
  7. 18. clips on top of stage that allow you to secure the specimen or slide.
  8. 21. a double-layered membrane that surrounds the cell. Also called the plasma membrane, it regulates what enters and leaves the cell.
  9. 22. a jelly-like substance, composed mainly of water, occupying most of the space between the cell membrane and the nucleus.
  10. 26. series of chemical reactions that convert energy in food molecules into ATP
  11. 30. series of reactions that convert light energy, water, and CO2 into glucose and give off oxygen
  12. 31. a round body in the center of the cell that contains DNA and regulates gene expression.
  13. 33. a simple sugar that serves as the major energy source for all cellular processes.
  14. 37. a network of passageways in which chemical compounds are manufactured, processed, and transported.
  15. 38. a small sac, or vesicle, that contains digestive chemicals
  16. 39. energy that is released or absorbed in chemical reactions
  17. 42. the outermost layer of a bacterial cell that prevents harmful materials from entering, keeps the cell from drying out, and protects the bacterial cell from the immune cells of other organisms.
  18. 43. made of many cells
  19. 44. a platform on top of the base of the microscope on which specimen are placed
  20. 46. lenses at the viewing end of a microscope
  21. 48. lens at the end of a microscope nearest the object
  22. 49. a portion of the microscope that allows you to switch back and forth between lens powers.
Down
  1. 1. a double-layered membrane that surrounds and protects the nucleus.
  2. 2. a stack of membranes that collects, modifies, and packages chemical compounds.
  3. 5. filaments, including actin, microtubules, and microfilaments, that aid in cell movement and give the cell its shape.
  4. 6. a hair-like organelle that helps a cell move.
  5. 7. A nonliving protective shell with genetic material inside of it.
  6. 8. a type of vesicle that stores water, nutrients, and other chemicals. The large vacuole found in plant cells helps the cells maintain their shape.
  7. 9. Genetic material that holds information for making more cells.
  8. 10. an organelle that converts the radiant energy of the Sun into chemical energy through the process of photosynthesis.
  9. 11. The chemical process in which carbon dioxide and water combine, using energy from the Sun, to make sugar and oxygen.
  10. 13. an organelle that uses oxygen to convert nutrients into energy that can be used by the cell.
  11. 15. on/off button that powers the light.
  12. 19. energy in the form of electromagnetic radiation
  13. 20. a bundle of microtubules that helps organize the movement of chromosomes during cell division.
  14. 23. a green pigment inside chloroplasts that converts light energy into a chemical form the plant can use
  15. 24. made of one cell
  16. 25. a region inside a bacterial cell that contains genetic material. Unlike in plant and animal cells, the nucleoid in bacteria is not surrounded by a nuclear membrane.
  17. 27. a small, sac-like package of nutrients, proteins, or water created by the Golgi apparatus. Types of vesicles include vacuoles and lysosomes.
  18. 28. living things are made of one or more cells; the cell is the smallest unit of life; new cells come from preexisting cells
  19. 29. a cell structure that performs a specific function.
  20. 32. a small, circular piece of DNA separate from the genetic material in the nucleoid of a bacterial cell. Plasmids often contain genes that provide an advantage to the cell, like antibiotic resistance.
  21. 34. a hair-like structure that helps bacterial cells adhere to surfaces. Some pili are able to transfer genetic material to other cells.
  22. 35. a tiny structure where proteins are synthesized
  23. 36. a small body in the nucleus where ribosomes are synthesized.
  24. 40. a chemical process that does not use oxygen
  25. 41. A type of single-celled organism found almost everywhere on Earth.
  26. 45. the rigid, porous outer layer of a plant cell.
  27. 47. The basic unit of all living things.
