  1. 1. An organelle that contains DNA and controls cellular activity.
  2. 4. A semi-rigid structure located outside of the plasma (cell) membrane in plant, fungal and bacterial cells.
  3. 9. The tight banding found in all chromosomes usually around the centre.
  4. 11. The structural, functional and biological unit of all organisms.
  5. 13. A type of cell division which results in 4 daughter cells being produced.
  6. 14. Any cells or organisms without a membrane-bound nucleus and other membrane-bound organelles.
  7. 15. A substance found in chromosomes and that is responsible for storing the genetic information of a particular organism.
  8. 18. A visual representation of all the chromosomes found in an organism.
  9. 19. A specialized sub-unit of a cell that has a particular function.
  10. 20. An organelle containing RNA that is the main site of protein production in cells.
  11. 23. A process of cell division undertaken by diploid cells, of which as a result 2 daughter cells are produced.
  12. 24. A type of cell found in gonads,that reproduce by meiosis.
  13. 25. Refers to a cell that contains 2 sets of paired chromosomes.
  14. 26. A complete set of genetic instructions for a given organism.
  15. 28. The ability cells have to self-destruct.
  16. 29. Refers to a cell that contains 1 set of unpaired chromosomes.

  1. 2. A cell with a membrane-bound nucleus and membrane-bound organelles.
  2. 3. Stage of mitosis during which chromosomes align around the equator of a spindle.
  3. 5. A period of cell growth and DNA synthesis during the mitotic cell cycle.
  4. 6. A segment of DNA that codes for a particular protein.
  5. 7. A cellular organelle involved in cellular division.
  6. 8. Different forms of a particular gene.
  7. 10. Any type of cell from an organism apart from reproductive cells and that reproduces by mitosis.
  8. 12. Clusters of microtubules that grow out from the centrioles at the opposite ends of a spindle.
  9. 16. Long and twisted strands of DNA.
  10. 17. Stage of mitosis in which chromosomes contract and become visible.
  11. 21. The cells produced after meiosis that form sperm or egg cells.
  12. 22. Stage of mitosis in which new nuclear membranes form around the separated groups of chromosomes.
  13. 27. A macromolecule that is made up of repeating amino acids and that is vital for the body to function properly.
