Across
  1. 6. Curved cells containing chloroplasts that surround a stoma. These cells open and close the stomata(pores)
  2. 8. Inner tissue (parenchyma) of a leaf, containing many chloroplasts. These cells are loosely packed and have many air spaces between them
  3. 9. Space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
  4. 12. A dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
  5. 13. Stored carbohydrate found in plants
  6. 14. Vascular tissue in plants which conducts sugars and other metabolic products downwards from the leaves.
  7. 15. Photosynthesizing cells containing chloroplasts Plastid in green plant cells which contains chlorophyll and in which photosynthesis takes place.
  8. 16. An organelle found in large numbers in most cells, in which the cellular respiration and energy production occur.
Down
  1. 1. A protective and waxy layer covering the epidermis of a plant
  2. 2. A layer of tall, thin cells containing many chloroplasts found under the upper epidermis of the leaf
  3. 3. Transparent cells found in the outer layer of a plant organ. These cells do not contain chloroplasts.
  4. 4. A simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
  5. 5. Strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.
  6. 7. Opening in the surface of leaves that allows gases to move in and out of the leaf
  7. 10. A large group of organic compounds found in cells, including glucose, sucrose, and starch.
  8. 11. A plastid in green plant cells which contains chlorophyll and in which photosynthesis takes place.
