Across
  1. 3. The gas given out by plants when photosynthesis is taking place.
  2. 4. The gas taken in by plants to allow photosynthesis to occur.
  3. 5. These cells open and close to allow gases to be exchanged. They take in carbon dioxide and release oxygen.
  4. 7. Large number of glucose molecules joined together. If it is present in leaves then photosythesis must have occured.
  5. 9. These plant cells are adapted to absorb water through the roots. They have a thin membrane and a long arm-like structure which makes them more efficent
  6. 10. They are the cells contained within the stem. They help transport water to the leaves.
  7. 11. They are thin and have a large surface area to absorb lots of light. They contain palisade cells, stomata and guard cells within.
Down
  1. 1. The type of energy which is produced by the plant to allow it to survive. It is a sugar based energy type, similar ro the energy used in humans.
  2. 2. One of the ways plants make food. The process of transferring light energy (sunlight) into glucose.
  3. 6. It is the green pigment contained within the chloroplast which allows photosynthesis to take place.
  4. 8. Within the palisade cell. They contain chlorophyll which allows photosynthesis to occur.
