cells

4. looked at a cork under the microscope and noticed little empty boxes that he called "cells"
7. making food by changing energy from the sun
8. respiration occurs when oxygen is present
10. gives the support and structure
12. all living things are made of cells
14. all plants are made of cells
16. pack up used proteins and move them out of the cell
17. the theory that living things come only from other living things
19. when nucleus divides to form 2 new cells
20. boiled broth in flasks
22. let's things in and out of the nucleus
23. controls what happens in the nucleus
24. the structure within the cytoplasm that carrys on specific jobs to make the cell function
25. the total of chemical activities of an organism that enable it to stay alive, grow, and reproduce
26. directs all activities that happen in the cell
28. moves out waste products
29. when the particle is too large to exit the cell so the material fuses with the cell membrane
30. water through the cell membrane

1. uses no energy to move particles in and out of the cell
2. provide the cell with protein
3. all animals are made of cells
5. organisms that make their own food, like plants
6. chromosomes-holds the DNA tells the cell information
9. is when materials need energy to help them move through a cell membrane
11. when the particle is too large to enter through active or passive transport
13. supplies the cell with water
15. respiration occurs when oxygen levels are low
18. outside the layer of the cell lets things in and out
21. that cannot make their own food like humans
27. gel like substance that moves things through the cell
