Biology

3. living organisms create new individual organisms, or offspring
4. a tough, natural sugar polymer that forms the protective outer skeletons of insects and crustaceans, as well as the cell walls of fungi
8. animal classification that includes all living and extinct animals
10. plant life in general or the total plant cover in a specific area
11. a strong, mesh-like polymer made of sugars and amino acids that forms the cell wall of most bacteria
14. any eukaryotic organism that is not an animal, plant, or fungus
17. tiny, single-celled reproductive units
18. an animal that has a backbone or spinal column
19. he process where plants, algae, and some bacteria use sunlight, water, and carbon dioxide to create food (glucose) and release oxygen

1. a living thing made of more than one cell
2. an animal that does not have a backbone or internal bony spinal column
5. living eukaryotic organisms
6. single-celled, eukaryotic microorganisms that lack a cell wall and behave in animal-like ways
7. any individual living system or being
9. biological kingdom that includes single-celled organisms with prokaryotic cells
12. make their own food using sunlight
13. chemical substances obtained from food that organisms need to live, grow, and stay healthy
15. allow certain organisms to convert carbon molecules into organic matter using energy from inorganic chemical reactions instead of sunlight
16. any system or life form that possesses or shows the fundamental characteristics of life
20. living things whose cells contain a distinct, membrane-bound nucleus and other specialized, internal compartments called organelles
