Across
  1. 4. looked at a cork under the microscope and noticed little empty boxes that he called "cells"
  2. 7. making food by changing energy from the sun
  3. 8. respiration occurs when oxygen is present
  4. 10. gives the support and structure
  5. 12. all living things are made of cells
  6. 14. all plants are made of cells
  7. 16. pack up used proteins and move them out of the cell
  8. 17. the theory that living things come only from other living things
  9. 19. when nucleus divides to form 2 new cells
  10. 20. boiled broth in flasks
  11. 22. let's things in and out of the nucleus
  12. 23. controls what happens in the nucleus
  13. 24. the structure within the cytoplasm that carrys on specific jobs to make the cell function
  14. 25. the total of chemical activities of an organism that enable it to stay alive, grow, and reproduce
  15. 26. directs all activities that happen in the cell
  16. 28. moves out waste products
  17. 29. when the particle is too large to exit the cell so the material fuses with the cell membrane
  18. 30. water through the cell membrane
Down
  1. 1. uses no energy to move particles in and out of the cell
  2. 2. provide the cell with protein
  3. 3. all animals are made of cells
  4. 5. organisms that make their own food, like plants
  5. 6. chromosomes-holds the DNA tells the cell information
  6. 9. is when materials need energy to help them move through a cell membrane
  7. 11. when the particle is too large to enter through active or passive transport
  8. 13. supplies the cell with water
  9. 15. respiration occurs when oxygen levels are low
  10. 18. outside the layer of the cell lets things in and out
  11. 21. that cannot make their own food like humans
  12. 27. gel like substance that moves things through the cell
