Across
- 1. protein rods and tubules that form a supportive framework.
- 4. fingerlike projections in the cell membrane which increase surface area of the cell.
- 5. is not covered in ribosomes so it looks smooth.
- 6. a network of membranes in the shape of flattened sacs or tubules
- 7. very small structures in the cytoplasm are assembled from protein and rRNA.
- 8. intracellular fluid, surrounds the organelles.
- 10. Membrane that allows some types of molecules through but not others.
- 11. The powerhouses of the cell. Generates ATP via aerobic respiration.
- 17. cells with specialized characteristics
- 21. Lipid Bi-layer made of phospholipids, gives the cell shape and protects it.
- 22. loger cilia, move the cell.
- 23. intracellular structures having a characteristic shapes.
- 24. organic molecules that stores and releases energy.
- 25. short hairlke projections from the cell membrane
- 26. membranes bounded packages pinched off from the golgi complex.
- 27. protein lined channel in the nuclear envelope.
- 28. proteins that guide movements of cells.
Down
- 2. Series of biochemical reactions that allows cells to receive and respond to messages coming through the cell membrane.
- 3. Membranous sacs that vary in size and content
- 9. the cell membrane is either permeable or impermeable to certain substances
- 12. a structure located in the cytoplasm near the nucleus.
- 13. the cellular contents between the cell membrane
- 14. connected to the nuclear envelope surface is covered with ribosomes making the ER look rough.
- 15. the movement of particles into and out of cells through the cell membrane is essential.
- 16. oval shaped structure stores DNA.
- 18. Stored in the nucleus of the cell
- 19. membranous sacs that resemble lysosmomes in size and shape.
- 20. also consists of flattened, membranous sacs, sorts package proteins.
