- 3. /prokaryotic/1having cells that lack membrane-bound nuclei
- 6. /eukaryotic/1having cells with `good' or membrane-bound nuclei
- 8. living things notice changes in the experiments around them and react.
- 14. /plasmid/1a small cellular inclusion consisting of a ring of DNA that is not in a chromosome but is capable of autonomous replication.
- 15. smallest unit of living matter that can exist on its own.All plants and animals are made up of it.

Down
- 1. /ribosome/1an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell
- 2. small part found in most cells,in which the energy in food is released.
- 4. membrane:the semipermeable membrane surrounding the cytoplasm of a cell.
- 5. ribosome is the site of protein synthesis.
- 7. structure in plant cells that contains chlorophyll and in which photosynthesis takes place.
- 9. lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
- 10. central part of some cells,containing the genetic material.
- 11. vacuole /vacuole/1a tiny cavity filled with fluid in the cytoplasm of a cell
- 12. action of breathing.
- 13. blood cell:mature blood cell that contains hemoglobin to carry oxygen to the bodily tissues; a biconcave disc that has no nucleus
