Across
- 7. -a plant structure in seed plants that produces the female gametophyte; contains an egg cell.
- 10. -a thin, rootlike structure that anchors a moss and absorbs water and nutrients for the plant.
- 12. -the process in sexual reproduction in which an egg cell and a sperm cell join to form a new cell.
- 13. -an organism that is able to capture energy from sunlight or chemicals and use it to produce its own food.
- 15. -a low-growing plant that lacks true vascular tissue for transporting materials.
- 19. -the waxy, waterproof layer that covers the leaves and stem of most plants.
- 21. -a leaflike structure that encloses and protects the bud of a flower.
- 22. -the vascular tissue through which water and minerals move in some plants.
- 23. -the young organism that develops from a zygote.
- 25. -the leaf of a fern plant.
- 26. -a plant that has a true vascular tissue for transporting materials.
Down
- 1. -the reproductive structure os an angiosperm.
- 2. -tiny structures (male gametophyte) produced by seed plants that contain the cell that later becomes a sperm cell.
- 3. -the transfer of pollen from male reproductive structures to female reproductive structures in plants.
- 4. -the vascular tissue through which food moves in some plants.
- 5. -a fertilized egg, produced by the joining of a sperm cell and an egg cell.
- 6. -the process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide.
- 8. -a sac-like organelle that stores water, food, and other materials.
- 9. -a flowering plant that completes its life cycle in two years.
- 11. -a plant with a flowering cycle that is not sensitive to periods of light and dark.
- 14. -a colorful, leaflike structure of some flowers.
- 16. -the internal transporting tissue in some plants that is made up of tubelike structures that carry water, food, and minerals.
- 17. -a plant that flowers when the nights are longer than the plant's critical night length.
- 18. -a plant that flowers when the nights are shorter that the plant's critical night length.
- 19. -the reproductive structure of a gymnosperm.
- 20. -the sprouting of the embryo out of a seed; occurs when the embryo resumes its growth following dormancy.
- 24. -an organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy for that cells can use in making food.
- 27. -a green photosynthetic pigment found in the chloroplast of plants, algae, and some bacteria.
- 28. -a flowering plant that lives for more than two years.
- 29. - a group of similar cells that perform a specific function.
