Across
  1. 1. Supports the slide/specimen
  2. 3. Used to vary the intensity of light that is projected upwards into the slide
  3. 5. Jelly-like substance where reactions happen
  4. 6. Help make babies-only males have
  5. 7. the taking in of matter by a living cell by invagination of its membrane to form a vacuole
  6. 13. The lens closest to the eye in a microscope
  7. 18. Contains chlorophyll-where photosynthesis happens
  8. 19. Contains cell sap-keeps the cell firm
  9. 20. one thousand-millionth of a metre
  10. 22. the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water
  11. 24. uses focused light and lenses to magnify a specimen, usually a cell
  12. 25. Increase magnification (usually from 10x to 40x)
  13. 26. Powerhouse of the cell-makes the energy
  14. 27. 3 parts are, All organisms are composed of one or more cells, The cell is the basic unit of structure and organisation in organisms, All cells come from preexisting cells
Down
  1. 2. the death of cells which occurs as a normal and controlled part of an organism's growth or development
  2. 4. one-millionth of a meter
  3. 8. increase magnification (usually from 10x to 40x)
  4. 9. Controls what happens in the cell (contains DNA)
  5. 10. Cary oxygen around the body
  6. 11. Allow you to detect touch, smell, taste, sound, light, pain
  7. 12. Makes up all living things
  8. 14. First person said to invent a compound microscope
  9. 15. cell division process that results in new cells with the same number of chromosomes as the original cell
  10. 16. an optical instrument for forming magnified images of small objects,
  11. 17. Cell that differs in several key aspects
  12. 21. First came up with the term 'The cell' after looking at a piece of cork under the microscope
  13. 22. exist at or from an earlier time
  14. 23. Keeps substances in the cell and controls what goes in and out
