Across
- 2. a differentially permeable layer composed of protein and lipid around the outside of the cell. Controls what enters and leaves the cell
- 5. a food store
- 8. contains water. Collects
- 11. slimy outer covering found in some bacteria. Protects the cell
- 12. a rod-shaped organelle with a smooth outer membrane and folded inner membrane.Contains respiratory enzymes. Where respiration occurs.
- 14. (false foot) – an extension of membrane and cytoplasm (used to engulf food and for movement in amoeba)
- 17. a food store
Down
- 1. long, whip-like projection. Aids in movement
- 3. surrounded by a double membrane,Chromatin threads contain genetic information in the form of DNA. Essential for cell division.
- 4. a jelly-like substance composed of about 80% water and 20% dissolved substances, especially protein. Supports the organelles and is the site of many chemical reactions
- 6. a disc-shaped organelle surrounded by a double membrane which contains chlorophyll
- 7. DNA region in prokaryotes which lacks a nuclear membrane, and also in smaller regions called plasmids.
- 9. cytoplasm and nucleus together referred to as__________.
- 10. small or large membrane-bound compartments.
- 13. is the basic structural and functional unit of living organisms.
- 15. structures which are specialised to carry out one or more vital functions, e.g. the nucleus, mitochondria, chloroplasts and vacuoles.
- 16. lack a true nucleus and other membrane-bound organelles.
- 18. removes excess water from the cytoplasm in amoeba
