Across
  1. 5. feature that contains male or female reproductive structures of cycads and other gymnosperms
  2. 6. type of plant with vascular tissues adapted to land environments; most widely distributed type of plant on Earth
  3. 7. compact cluster of spore-bearing structures in some seedless vascular plant sporophytes
  4. 10. plant that lives anchored to an object or to another plant
  5. 11. thin cylinder of meristenatic tissue that produces new transport cells
  6. 15. type of plant that lacks vascular tissues, moves substances slowly from cell to cell by osmosis and diffusion, and grows only in damp environment
  7. 17. sac or case in which fungal spores are produced
  8. 18. Livewort with a fleshy, lobed body shape
  9. 19. basic unit of structure and organization of all living organisms
  10. 20. seed structure that stores food or helps absorb food for the sporophyte of vascular seed plants
Down
  1. 1. spherical, thin-walled cell found throughout most plants that can function in photosynthesis, gas exchange, protection, stroage, and tissue repair and replacement
  2. 2. often elongated plant that provides flexibility for the plant, support for surrounding tissues, and functions in tissue repair and replacement
  3. 3. plant that can live for several years
  4. 4. plant cells that lacks cytoplasm and other living components when mature, leaving thick rigid cell walls that provide support and functions in transport of materials
  5. 8. fern's thick underground stem that functions as a food-storage organ
  6. 9. openings in the outer cell layer of leaf surfaces and some stems that allow the exchange of water, carbon dioxide, oxygen, and other gases between a plant and its environment
  7. 12. plant with a two-year life span
  8. 13. specialized tissue that transports water, food, and other substances in vascular plants and can also provide structure and support
  9. 14. fern structure formed by clusters of sporangia, usually on the undersides or a frond
  10. 16. plant that completes its life span in one growing season or less
  11. 17. adaptive reproductive structure of some vascular plants that contains an embryo, nutrients for the hardening of the embryo, and is covered by a protective coat
