Biology

2. The green pigment in plants and algae that absorbs light energy for photosynthesis.
5. A structural carbohydrate found in the cell walls of plants and some other organisms.
7. The process by which organisms increase in size and complexity over time.
10. The process by which organisms eliminate waste products from their body.
12. The gel-like substance that fills the interior of cells and contains organelles, proteins, and other molecules.
13. The organelles in eukaryotic cells that produce energy in the form of ATP.
14. The organelle in eukaryotic cells that contains the cell's genetic material, or DNA.
15. Membrane-bound structures in eukaryotic cells that store water, nutrients, and waste products.
16. The process by which organisms produce offspring to continue their species.
19. A small, circular piece of DNA found in some bacteria that can replicate independently of the chromosomal DNA.
20. The metabolic process by which cells use oxygen to convert nutrients into energy and produce carbon dioxide as a waste product.

1. Organisms with cells that contain a nucleus and other membrane-bound organelles.
3. Single-celled organisms that lack a nucleus or other membrane-bound organelles.
4. The ability of organisms or their cells to move from one place to another.
6. The organelle in plant cells that carries out photosynthesis.
8. membrane: The thin, flexible barrier that surrounds cells and regulates the movement of materials in and out of the cell.
9. The ability of organisms or cells to respond to changes in their environment or stimuli.
11. A type of fungus that is used in baking and brewing, and can ferment sugars into alcohol and carbon dioxide.
12. wall: A rigid outer layer that provides additional support and protection for cells in plants, fungi, and some bacteria.
17. The cellular structure responsible for synthesizing proteins.
18. The process of obtaining and using nutrients from food to support bodily functions.
