  1. 3. A cell that contains a nucleus and membrane-bound organelles
  2. 4. A biomolecule that performs various functions, including functioning as enzymes; transporting molecules, antibodies, and hormones; and providing structure
  3. 5. Converts energy from food into energy a cell can use
  4. 9. A nonliving, infectious agent that cannot reproduce without a host, obtain or use energy, or respond to the environment
  5. 12. A protein that acts a biological catalyst
  6. 14. Regulates what goes into and out of the cell
  7. 16. Fluid that surrounds the organelles
  8. 17. A cell organelle composed of RNA; responsible for synthesizing proteins
  9. 18. A large molecule synthesized by cells that form the structures of cells and perform the functions of life
  10. 19. The basic unit of structure and function in living organisms
  11. 21. A nucleic acid that is self-replicating and contains the genetic code to make all proteins needed by an organism
  12. 22. Gives structure and rigidity to plant cells
  13. 23. Made of DNA located in the nucleus; contains genetic information needed to carry our cell functions and make new cells

  1. 1. Theory of how organelles arose in eukaryotic cells; proposes that organelles evolved internally within cells from the folding and internalization of the cell’s own membranes
  2. 2. A biomolecule that performs various functions, including cell membrane structure, long-term energy storage, and insulation
  3. 6. Organisms that are made of one cell
  4. 7. A cell that does not have a nucleus and membrane-bound organelles
  5. 8. A biomolecule that stores genetic information
  6. 10. Theory of how organelles arose in eukaryotic cells; proposes that certain organelles, specifically mitochondria and chloroplasts, were free living prokaryotes that were engulfed by a host cell, leading to a mutually beneficial relationship
  7. 11. Site of photosynthesis in plant cells
  8. 13. A group of 20 chemicals that bond together to create a polypeptide chain (protein)
  9. 15. Organisms made up of multiple cells
  10. 20. Contains genetic material and controls the use of genes; found in eukaryotic cells
  11. 24. Storage area for water and waste within cells
