Across
  1. 1. site – the specific part of an enzyme which connects to the substance to be catalysed
  2. 3. – the type of cell in a plant which allows water to travel through it (it has no ends, like a tube)
  3. 5. – a process in which the cells use energy absorbed from the surroundings
  4. 7. – used to test for starch
  5. 8. – when the vacuole has some liquid to hold the shape of the cell
  6. 11. – the movement of sugars and other chemicals made by a plant along the phloem
  7. 12. – the sugar made by plants during photosynthesis
  8. 13. – the process in which a plant produces its own energy
  9. 15. – the movement of a substance with the concentration gradient (from high to low) that is a passive process
  10. 16. – produces the energy in a cell
  11. 17. – the type of cell which transports sugars and has a partially permeable membrane on the end.
  12. 18. – a non-living factor that can affect an ecosystem
  13. 20. – the green substance in plants which enables photosynthesis to take place
  14. 21. – the comparison of concentrations between two different concentrations
  15. 24. – used to test for glucose
  16. 26. – when the vacuole has shrunk due to lack of water
  17. 28. – an organism that produces its own food
  18. 29. – the spread of a substance which requires no energy (it is passive)
  19. 31. – used to test for protein
  20. 32. – the movement of water (usually from high to low concentration)
Down
  1. 2. – a substance which speeds up a chemical reaction
  2. 4. - a factor which inhibits a process from taking place
  3. 6. – the stores of the green substance in a plant that is required for photosynthesis
  4. 9. – a living factor that can affect an ecosystem
  5. 10. – an organism that cannot produce its own food (it needs to be a consumer)
  6. 14. – the space in the middle of a plant cell
  7. 15. – the name given to a membrane that has small holes in it to allow small molecules to pass through it
  8. 19. – a biological catalyst
  9. 22. – used to test for fat
  10. 23. – the movement of a substance agains the concentration gradient (from low to high) which requires energy
  11. 25. – the movement of water along the xylem in a plant
  12. 27. – when the vacuole has lots of water in it and the cell has been stretched
  13. 30. – a tool used to sample an ecosystem
