Across
  1. 3. Specialized junctions that anchor cells together, providing mechanical strength to tissues.
  2. 4. Breaks down fatty acids and detoxifies harmful substances.
  3. 6. Studded with ribosomes; involved in protein synthesis and modification.
  4. 7. Organizes microtubules and contains centrioles (in animal cells); important in cell division.
  5. 10. The powerhouse of the cell, generates ATP through cellular respiration.
  6. 14. Thin fibers of actin involved in cell shape, movement, and muscle contraction.
  7. 17. Selectively permeable barrier made of phospholipids and proteins that separates the interior of the cell from the outside environment.
  8. 18. Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
  9. 20. Found in plant cells; performs photosynthesis.
Down
  1. 1. Network of fibers that provide structural support, shape, and facilitate cell movement.
  2. 2. Synthesizes lipids, detoxifies drugs, metabolizes carbohydrates.
  3. 5. Hollow tubes of tubulin that help maintain cell structure and shape.
  4. 8. Found inside nucleus; site of rRNA synthesis and ribosome assembly.
  5. 9. Site of protein synthesis; can be free in the cytoplasm or attached to rough ER.
  6. 11. Contains cell’s genetic material and controls cell activities.
  7. 12. ________ Filaments - Provide mechanical strength to cells and anchor organelles in place.
  8. 13. Contain digestive enzymes for breaking down macromolecules, debris, and foreign substances.
  9. 15. _____ Junctions - Channels that allow direct communication between adjacent animal cells, facilitating the exchange of ions and small molecules.
  10. 16. Large vesicle used for storage, waste disposal, and maintaining cell turgor in plant cells.
  11. 19. _____ Junctions - Seal gaps between adjacent cells, preventing the leakage of extracellular fluids.
