Across
  1. 2. Large biological molecules essential for life, including carbohydrates, lipids, proteins, and nucleic acids.
  2. 5. Generation An outdated theory that life arises from nonliving matter.
  3. 6. Single-celled prokaryotes similar to bacteria but genetically distinct and often found in extreme environments.
  4. 8. The theory that living organisms arise only from other living organisms.
  5. 10. Acids Informational macromolecules (DNA and RNA) that store and transmit genetic information.
  6. 11. Microorganisms that cause disease in humans or other organisms.
  7. 12. Cells that do not have a nucleus or membrane-bound organelles; includes bacteria and archaea.
  8. 13. Macromolecules made of glycerol and fatty acids that store energy and make up cell membranes.
  9. 14. Polymers made of amino acids that perform many functions such as enzymes and antibodies.
  10. 16. Infectious, nonliving proteins that contain no nucleic acid and cause diseases such as mad cow disease.
Down
  1. 1. Tiny living organisms that include bacteria, archaea, protozoa, fungi, algae, and microscopic stages of worms; viruses and prions are exceptions because they are nonliving.
  2. 3. Single-celled, prokaryotic microorganisms that lack a nucleus and membrane-bound organelles.
  3. 4. Carbohydrate polymers made of many sugar units that store energy and provide structural support in cells.
  4. 7. Nonliving, acellular particles made of DNA or RNA surrounded by a protein coat that must infect a host cell to reproduce.
  5. 9. A branch of biology that studies microorganisms, which are living things too small to be seen without a microscope.
  6. 15. Cells that contain a nucleus and membrane-bound organelles; found in organisms like fungi, protozoa, algae, plants, and animals.
