Across
  1. 5. Allow small molecules and ions to flow between the cytoplasm of adjacent cells.
  2. 7. Extracellular structure that distinguishes plant and animal cells.
  3. 11. A cell engulfing another, smaller, cell by forming a food vacuole.
  4. 16. Flattened membranous sacs of the Golgi Apparatus
  5. 17. Receptor proteins in the plasma membrane that bind to proteins in the extracellular matrix.
  6. 18. Responsible for maintaining shape of nucleus.
  7. 21. Create flexible adherence points that are anchored beneath the plasma membrane by the cytoskeleton.
  8. 22. Composed of glycoproteins collagen, proteoglycans, and fibronectin and is found in animal cells.
  9. 23. Form between adjacent cells.
  10. 25. Made of rRNA and protein and carry out protein synthesis.
  11. 26. A compartment created by the inner membrane of the mitochondria where some metabolic steps of cellular respiration are catalyzed.
  12. 27. Plasma membrane-lined channels that connect the cytosols of adjacent cells.
  13. 28. A layer of pectin that holds walls of adjacent cells together.
  14. 29. Interconnected system of protein fibres and tubes that extend through the cytoplasm to maintain shape, organization, movement, and vesicular transport within animal cells.
  15. 30. Process through which lysosomes recycle a cell's own organelles and macromolecules.
Down
  1. 1. A stack of thylakoids in a chloroplast.
  2. 2. This part of a plant's cell wall is soft and flexible.
  3. 3. Consists of tubulin and is responsible for cell locomotion as well as for chromosomal configuration during mitosis.
  4. 4. These fibres compose plant cell walls.
  5. 6. First groups of bacteria to evolve, could oxidize water to produce oxygen.
  6. 8. Polymer containing sugars and polypeptides that plays an important role in forming the cell walls of bacteria.
  7. 9. Contains DNA and proteins that form chromosomes.
  8. 10. Folds in the membrane of mitochondria that allow for more surface area to be used by enzymes that synthesize ATP.
  9. 12. Discrete units that contain DNA.
  10. 13. Organelles increase their quantity of membrane as a function of their ______ .
  11. 14. Composed of many different proteins, mostly keratins, and is responsible for tissue specific roles and forming nuclear lamina.
  12. 15. Consists of actin and is responsible for muscle contraction and cell division.
  13. 19. Specialized unit of the nucleus where rRNA is synthesized and ribosomal subunits are formed.
  14. 20. Molecules that are both hydrophobic and hydrophilic.
  15. 24. This part of a plant's cell wall contains additional layers of cellulose and branched carbohydrates.
