Across
  1. 5. Rigid later of cells found only in plants
  2. 6. Part of mitochondria (the folds) where the electron transfer chain occurs
  3. 7. The stage in the cell cycle where the replicated chromosomes are checked for mistakes
  4. 8. Full name for DNA
  5. 9. Respiration in the presence of oxygen
  6. 11. An enzyme which takes large molecules and breaks them up
  7. 18. A form of active transport where fluids and nutrients are ingested by cells
  8. 20. Site of photosynthesis
  9. 21. Pigment found in plants which gives the plant it's green colour
  10. 22. Part of chloroplast where the light stage occurs
  11. 23. The stage of the cell cycle where the replicated chromosome is split into 2 cells
  12. 24. The model explaining how enzymes work where the enzyme is a rigid structure
  13. 25. A specific shaped part of an enzyme where the substrate fits
  14. 26. The movement of materials from an area of high concentration to an area of low concentration
  15. 28. The stage in the cell cycle where the DNA is replicated
  16. 30. A solution with a low concentration of solute, therefore a high concentration of water
  17. 31. The movement of molecules from an area of high concentration to an area of low concentration which doen't require energy
  18. 32. A slolution with a high concentration of solute, therefore a low concentration of water
  19. 33. A membrane that allows some substances to pass through it but not others
  20. 34. Biological catalysts which speed up biochemical reactions in an organism
  21. 35. The enzyme model where the enzyme changes its shape after bonding with the substrate
  22. 37. The changing in the shape of the active site of an enzyme, so the substrate can no longer fit- caused by high temperatures and incorrect pH
  23. 38. Part of the mitochondria where the citric acid cycle occurs
  24. 39. The net movement of water through a semi-permeable membrane from an area of high concentration to an area of low concentration
  25. 40. The movement of molecules from an area of low concentration to an area of high which requires energy
Down
  1. 1. A form of passive transport where molecules move across the cell membrane through the membrane proteins
  2. 2. Respiration with limited oxygen
  3. 3. layer Part of the lead where most chloroplasts are found, so most photosynthesis occurs here
  4. 4. A form of active transport by which a cell uses it's plasma membrane to engulf a large solid particle
  5. 10. Part of a cell where proteins are modified and packaged
  6. 12. Organelle in the cell where respiration occurs
  7. 13. Part of cell where protein synthesis occurs
  8. 14. Part of chloroplast where the dark stage occurs
  9. 15. The name that describes that fact that the new DNA molecule being one strand new and one strand old
  10. 16. enzyme An enzyme that takes small molecules and joins them together
  11. 17. A cell that is limp and floppy
  12. 19. Poisons that bind to the active site of enzymes and stop them working
  13. 22. The stage in the cell cycle where the cell grows and does its job
  14. 27. A solution which has the same osmolarity or solute concnetration as another splution
  15. 29. The copying of DNA before the cell divides
  16. 36. A cell that is it is swollen, bloated, puffed up or inflated
