Across
  1. 3. extra dense area of almost pure DNA and protein found in the nucleus involved in the production of ribosomes and control of growth and division
  2. 4. cytoplasmic bridges between plant cells that allow communication between the cells
  3. 8. protein fibres that make up part of the structure of the cytoskeleton
  4. 11. ribosomes found in the mitochondria and chloroplasts of eukaryotic cells and in prokaryotic organisms
  5. 12. inside the cell
  6. 14. the main type of ribosomes found in eukaryotic cells
  7. 15. a smooth tubular reticulum without ribosomes involved in the synthesis and transport of steroids and lipids in the cell
  8. 17. tiny protein tubes that make up part of the structure of the cytoskeleton
  9. 19. rod-like structures with inner and outer membranes that are the site of aerobic respiration
  10. 22. the energy-requiring process by which a vesicle fuses with the cell surface membrane so the contents are released to the outside of the cell
  11. 23. cytoplasm and nucleus combined
  12. 24. a set of overlapping protein microtubules running the length of the cell
Down
  1. 1. consists of stacks of membranes that modify proteins made elsewhere in the cell and package them into vesicles for transport
  2. 2. a 3D network of membrane-bound cavities in the cytoplasm that links to the nuclear membrane and makes up a large part of the cellular transport system
  3. 5. a freely permeable wall around plant cells, made mainly of cellulose
  4. 6. an organelle full of digestive enzymes used to break down worn out cells or organelles, or digest food in simple organisms
  5. 7. an endoplasmic reticulum covered in 80S ribosomes, involved in the production and transport of proteins
  6. 9. an organelle containing nucleic acids as well as protein, surrounded by a nuclear envelope with pores
  7. 10. infoldings of the inner membrane of the mitochondria which provide a large surface area for the reactions of aerobic respiration
  8. 13. the granular combination of DNA bonded to protein found in the nucleus when the cell is not actively dividing
  9. 16. a fluid-filled cavity within the cytoplasm of a cell surrounded by a membrane
  10. 18. a jelly like liquid that makes up the bulk of a cell and contains organelles
  11. 20. 3D web like structure made up of microfilaments and microtubules filling the cytoplasm and giving it its structure
  12. 21. bundles of tubules found near the nucleus and involved in cell division
