Across
- 2. Do not have membrane bound structures
- 3. Tough outer covering of plant cells that protects and keeps its shape
- 6. Made of 2 or more different types of tissues that work together
- 8. A lipid bilayer with embedded proteins.
- 10. Green, double-membraned organelles containing chlorophyll.
- 11. Group of similar cells that work together
- 14. Found in nucleus and makes ribosomes
- 15. Jelly-like fluid that fills the cell.
- 16. The widely accepted belief that all living things are composed of individual cells along with the fact that all cells come from other cells
- 17. Structures that carry on the cell’s processes
- 19. Large, fluid-filled sacs found mainly in plant cells.
- 20. deliver materials throughout the cell
Down
- 1. Network of protein filaments (microtubules, actin filaments, and intermediate filaments).
- 4. Small, spherical structures either floating freely in the cytoplasm or attached to the rough endoplasmic reticulum (ER).
- 5. Oval-shaped, double-membraned organelles with inner folds called cristae
- 7. Stacks of flattened membranous sacs.
- 9. Large, membrane-bound organelle containing the cell's DNA. Surrounded by a double membrane called the nuclear envelope.
- 12. Have membrane bound structures
- 13. A network of membranes extending from the nuclear envelope, with two types: rough ER (studded with ribosomes) and smooth ER.
- 18. Small, spherical organelles containing digestive enzymes.
