Across
- 4. Small pores in plant leaves and stems that regulate gas exchange, allowing carbon dioxide to enter and oxygen to exit. *
- 5. Wall The rigid outer layer of a plant cell that provides structural support and protection. *
- 6. The process by which a seed begins to sprout and grow into a new plant. *
- 10. Offspring resulting from the cross-breeding of two different plant varieties or species. *
- 11. A flowering plant that produces seeds enclosed within a fruit. *
- 14. A seed-bearing plant that does not produce flowers, typically having cones and needle-like or scale-like leaves. *
- 15. The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, carbon dioxide, and water. *
- 17. A large geographic area characterized by its climate, vegetation, and wildlife. *
- 18. The process of fusion of male and female gametes to form a zygote, leading to the development of a new organism. *
- 20. The often colorful, leaf-like structures of a flower that attract pollinators. *
- 21. Fine powder produced by male reproductive organs of seed plants, containing the male gametes. *
- 22. The genetic makeup or genetic constitution of a plant, determining its hereditary characteristics. *
- 23. A green pigment found in chloroplasts that absorbs light energy during photosynthesis. *
Down
- 1. The outermost part of a flower, typically green and protective of the flower bud. *
- 2. The observable characteristics or traits of a plant resulting from its genetic makeup and environmental influences.
- 3. The male reproductive organ of a flower, consisting of the anther and filament. *
- 7. Undifferentiated plant tissue responsible for growth and development, found at the tips of roots and shoots. *
- 8. The vascular tissue in plants responsible for transporting water and nutrients from the roots to the rest of the plant. *
- 9. The embryonic seed leaf of a plant, which often stores nutrients for germination. *
- 12. The female reproductive organ of a flower, consisting of the stigma, style, and ovary. *
- 13. A plant that completes its life cycle in one year or growing season, typically flowering and setting seed during that time. *
- 16. Chemical messengers produced by plants that regulate growth, development, and responses to environmental stimuli. *
- 17. The scientific study of plants, including their structure, growth, reproduction, metabolism, and classification. *
- 19. A plant that lives for more than two years, often flowering and producing seeds repeatedly. *
- 20. The vascular tissue in plants responsible for transporting sugars, amino acids, and other organic molecules throughout the plant. *
