Across
  1. 1. Specialized leaf cells containing one large oil body and lacking chloroplasts
  2. 4. Unique organelle in liverwort leaf cells, absent in mosses and hornworts
  3. 6. Thread-like structure that grows when a spore germinates
  4. 7. Special basal-corner leaf cells that control leaf movement
  5. 8. Hood-like tissue covering the developing capsule
  6. 9. Cell wall thickenings found at the corners of leaf cells in some liverworts
  7. 12. Depend on moisture in the environment
  8. 13. Specialized conducting cells inside bryophytes
  9. 16. Anchoring to the substrate
