Across
- 5. A larger, more complex cell that stores its DNA in a nucleus. Animals and plants contain eukaryotic cells. These cells contain membrane-bound organelles.
- 9. The flexible outer covering surrounding every cell. It allows some things to pass through it, and others cannot pass through. Can be composed of one or more layers.
- 11. A stable internal environment
- 13. Storage areas for water, food, or waste products. Plants have a large central vacuole for water storage, while animal cells may have a few smaller vacuoles for waste.
- 14. A jell-o like fluid surrounding cell structures. Contains nutrients and water for the cell.
- 15. The rigid, outer layer of the cell that provides protection and support, surrounding the cell membrane. Found in plants, fungi and some bacteria only.
- 16. The “powerhouse of the cell”. Transforms food into energy.
- 17. Captures sunlight and converts it into energy through the process of photosynthesis. Only found in plant cells.
- 18. The “janitors” of the cell. Digests old, worn out cell parts. Found only in animal cells.
Down
- 1. Large, central organelle that contains DNA.
- 2. Makes proteins for the cell. The proteins they make can be either floating freely in the cytoplasm or attached to the rough endoplasmic reticulum.
- 3. 2 different types - smooth and rough E.R. (E.R. = endoplasmic reticulum). Smooth E.R. = has no attached ribosomes and detoxifies substances. Rough E.R. = has attached ribosomes and this is where proteins are made and modified.
- 4. A structure located in the cytoplasm of a cell that has a specific function.
- 6. A very small, simple cell that has no nucleus. Bacteria (a single celled organism) is an example. Does NOT contain any organelles. They were the first organisms on Earth.
- 7. An individual living thing
- 8. The basic unit / building blocks of life.
- 10. The genetic material located in the nucleus that is the basis for all life.
- 12. Sorts and ships molecules like FedEx. Modifies & moves proteins from the ribosomes on the Rough E.R.
