Across
- 3. a small plant without vascular tissue; also called a bryophyte
- 5. plant with vascular tissue but no seeds or flowers
- 9. type of tissue in plants that transports fluid throughout the plant; consists of xylem and phloem
- 11. group of specialized cells of the same kind that perform the same function
- 16. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar
- 17. vascular seedless plant with large divided leaves called fronds; more plant-like than the clubmosses; have stems, leaves, and roots
- 18. vascular seedless plant with hollow, ribbed stems; it is often found in marshes
- 19. the finely divided leaf of ferns; has fiddlehead shapes
- 21. of or relating to water, such as an organism that lives in water rather than on land
Down
- 1. type of vascular tissue in a plant that transports food from photosynthetic cells to other parts of the plant
- 2. a group of organisms that can mate with one another to produce fertile offspring
- 4. physical environment in which a species lives and to which it has become adapted
- 6. structure produced by a seed plant that contains an embryo and food supply enclosed within a tough coat
- 7. type of vascular tissue in a plant that transports water and dissolved nutrients from roots to stems and leaves
- 8. a tiny nonvascular plant that appears like green "fuzz" with tiny stem-like and leaf-like structures
- 10. vascular plant similar to the nonvascular moss, but with roots, stems, and leaves; similar to early vascular plants.
- 12. any substance in food that the body needs
- 13. organ of a plant that holds the plant upright to get light and air and may also bear leaves, flowers, and/or cones
- 14. chemical element such as calcium or potassium that is needed in relatively small amounts for proper body functioning
- 15. dominated by trees and other woody vegetation and are classified based on their latitude; include tropical, temperate, and boreal forests (taiga)
- 20. plant organ that generally grows down into the soil to absorb water and nutrients from the soil
