Across
- 2. hollow tubes made with proteins that keep everything is place
- 3. ATP
- 5. two short cylinders of microtubules that make right angles, involved in cell division
- 8. small organelle that move energy from organic molecules to ATP
- 9. made of a polar head and two non-polar fatty acid tails
- 12. can be in plant cells and some eukaryotic algae, main molecule that absorbs light energy for the cell
- 16. plant cells only, surrounded by double membrane, has its own DNA,
- 19. a structure in the nucleus made of DNA and protein
- 21. RNA
- 22. long hairs the help move the cell, there are a few of them on a cell
- 23. plant cells only, flattened membranous sacs that contain chlorophyll
- 24. a place in the nucleus with concentrated DNA
Down
- 1. organelles made of proteins and RNA that direct protein synthesis in the cytoplasm
- 4. Phospholipids side-by-side with the tails facing in toward more phospholipids' tails. The heads face outward (toward water) and the tails face inward (away from water.)
- 6. small hairs that help move the cell, there are a lot of them on a cell
- 7. threads with protein that help move the cell
- 10. DNA
- 11. system that can be rough (with ribosomes on it) or smooth (makes lipids), it is sometimes called ER
- 13. vesicles from Golgi body that contains digestive enzymes
- 14. plant cells only, type of plastid, uses light energy to make carbohydrates from carbon dioxide and water
- 15. network of filaments and thin tubes that keeps everything in place
- 17. post office of the cell, packs and processes proteins
- 18. layer outside of the plasma membrane
- 20. double membrane around nucleus that is made of two phospholipid bilayers with engrained proteins
