Across
- 2. / Holds the slide in place
- 5. / All living things are made of these
- 6. Adjustment Knob / The knob that moves the stage up and down
- 8. Source / Shines a bright light through the microscope to make viewing objects easier
- 10. / The man who discovered all plants have cells
- 13. / Rotating dial that controls the passage of light through the stage
- 16. Power Objective / The lowest lens setting
- 17. Wall / rigid supporting layer surrounding the cells of plants
- 18. / organelle that contains chemicals that breaks down large particles into small ones
- 19. and Base / Always carry the microscope by holding these two parts
- 22. organelles that convert energy to food molecules to energy the cell can use for functions
- 24. Tube / Passes light from the head to the eyepiece
- 25. / the thick fluid region of the cell
- 27. / Where one views the enlarged
- 30. Cell Theory / A scientific theory stating that all living things are made of cells
- 31. Body / organelle that receives proteins and other newly formed materials

Down
- 1. / Supports the microscope
- 3. / About how many cells make up an organism
- 4. / Supports the lenses, mirrors, and body tube (microscope should be carried by holding the base and this)
- 5. Vacuole / a sack like organelle that stores food, water, waste, and other materials
- 7. / (contains DNA) the genetic material that carries information about the organism
- 9. / Hooke looked at a dead sample of this
- 11. / This organelle produces photosynthesis
- 12. Membrane / the membrane surrounding the nucleus

- 16. The first person to witness living cells
- 20. / organelles in cytoplasm that produce proteins
- 21. / The man who discovered that all cells come from other living cells
- 23. Power Objective / The highest lens setting
- 25. / A threadlike structure in a cell's nucleus that contains DNA passed from one generation to the next Nucleolus / The small round structure in the nucleus where ribosomes are made
- 26. Samples / Leeuwenhoek looked at these samples
- 28. Button / Turns on and off the microscope
- 29. Microscope / A microscope with two eye pieces
