Across
- 3. Robert Hooke described cells as
- 6. most cells are what type
- 7. spherical organelles that degrade hydrogen peroxide
- 9. hair like organelles on outside of cell
- 14. membrane bound organelle that contains the cell's DNA
- 15. only found in plant cells, acts as an additional barrier around the cell
- 16. semi permeable membrane around the cell
- 17. which type of cell has a cell wall
- 18. nine sets of triplet microtubules that divide cells
- 20. powerhouse of cell that turns food to energy
- 22. made of two subunits, and carries out protein synthesis
- 23. membrane around the nucleus
- 24. partner to cilia
- 25. gel like fluid inside cell membrane
Down
- 1. network of thin fibrous elements that provide support for the cell
- 2. bacteria are this type of cell
- 4. stacked flat stacks that distribute proteins
- 5. sac of fluid surrounded by cell membrane for storage, large one in plant cells
- 8. acts as intracellular highway but has no ribosomes covering it
- 9. only found in plant cells, site of photosynthesis
- 10. part of cell that breaks down food particles and invading objects
- 11. acts as the intercellular highway and ribosomes covering it
- 12. Schleiden, Schwan, and Virchow made this theory
- 13. allows small molecules to pass into or out of nucleus
- 19. place where ribosomes are made
- 21. cells come from other cells, true or false
