  1. 3. This endoplasmic reticulum (ER) is covered with ribosomes and functions to synthesize and transport proteins.
  2. 4. This organelle moves DNA/chromosomes during animal cell division.
  3. 5. This endoplasmic reticulum (ER) makes and transports lipids.
  4. 6. Cells that have no nucleus and free-floating DNA, e.g. bacteria.
  5. 14. The fluid that fills cells.
  6. 16. Muscle cells have many mitochondria so they can produce lots of __________.
  7. 17. This organelle produces proteins and can be found on the rough ER or floating in the cell.
  8. 18. A flexible, permeable barrier surrounding all cells.
  9. 19. The "mailman" of the cell, this organelle packages and transports proteins and lipids within and out of the cell.
  10. 21. Cells that have a nucleus and membrane-bound organelles, e.g. animal cells.

  1. 1. The "digestive system" of animal cells, this organelle breaks down cell waste.
  2. 2. Leaf cells have many chloroplasts so they can perform ______________ to make food for the plant cell.
  3. 7. A rigid support for the outside of plant cells.
  4. 8. This organelle stores water, nutrients, and waste products.
  5. 9. This organelle provides internal structural support/shape to all cells.
  6. 10. The "brain" of the cell that contains DNA.
  7. 11. The "powerhouse of the cell", this organelle produces ATP (cell energy).
  8. 12. "Mini organs" in eukaryotic cells that perform unique functions for the cell.
  9. 13. This organelle contains chlorophyll and performs photosynthesis.
  10. 15. Red blood cells lack nuclei so they can carry more ____________.
  11. 20. Nerve cells lack centrioles, telling us they do not ___________.
