Across
  1. 2. The holes in leaves through which gases diffuse
  2. 4. It makes red blood cells red

  4. 6. Where water is absorbed by a plant (4,4,5)
  5. 8. It is a waste product of photosynthesis
  6. 10. Part of the blood that transports glucose and carbon dioxide
  7. 11. Part of the leaf that has spaces to allow gases to diffuse (6,5)
  8. 12. These organisms are at the bottom of the food chain and make their own food
  9. 13. The product of photosynthesis that is used in respiration
  10. 14. The minerals needed for healthy plant roots
  11. 15. It is needed to make chlorophyll
  12. 16. Needed for healthy leaves and flowers
