Cells
Across
- 4. thin flexible layer made of phospholipids, let's things in and out of cells
- 7. movement of materials across the cell membrane using cellular activity
- 8. only in plants-captures energy from sunlight to make energy the plant cell can use
- 10. large particles are engulfed by the cell which changed shape to accomodate
- 13. molecules from an area of high concentration to low concentration
- 16. made of one cell (bacteria, amoeba)
- 17. a process where the cell membrane uses a channel to allow molecules in and out of the cell easily
- 18. only in plant cells rigid outer supporting layer
- 19. produces proteins, a key piece of building blocks within the cell
- 21. tiny cell structure that carries out specific functions
- 22. diffusion of water molecules across a selectively permeable membrane
- 24. processes lipids
Down
- 1. break down old cell parts and recycle materials to be used again
- 2. large particles are released by the cell after changing shape to accomodate
- 3. moving materials across the cell membrane without the use of energy
- 5. convert food energy into energy the cell can use to live and function
- 6. contains the cells genetic material (DNA) controls many of the cells activities
- 9. stores water and food that the cell might need also acts as a trash can because it collects unneeded material
- 11. filler between the membrane and nucleus, supports all organelles (pool)
- 12. some substances can cross the membrane while others cant
- 14. made of many cells
- 15. recives proteins plus other formed materials from the ER packages them and sends them else where
- 20. produces ribosomes
- 23. basic unit of structure and function in ALL living things
