Biology

4. An organism that produces its own food from simple inorganic substances, like plants.
7. The organelle in plant cells that contains chlorophyll and is the site of food production.
8. The tough, rigid carbohydrate that forms the cell walls of plant cells.
10. Small organelle responsible for protein synthesis; found in all living cells.
11. The main storage carbohydrate found in animal cells and fungi.
12. A simple cell or organism (like bacteria) that lacks a true central control unit and other membrane-bound organelles.
13. Thread-like filaments that make up the body of a fungus.
14. Small, circular pieces of DNA found in bacteria outside the main chromosome.

1. The process that releases energy from food, usually involving oxygen.
2. A cell or organism that has a membrane-bound compartment and organelles.
3. The large, central organelle in advanced cells that contains the genetic material (DNA).
5. The process used by plants and other organisms to convert light energy into chemical energy.
6. The "powerhouse" of the cell; site of aerobic chemical breakdown.
9. A biological catalyst, usually a protein, that speeds up a specific chemical reaction.
15. The mass of branching filaments that forms the vegetative part of a fungus.
