Скачать или смотреть Flowers Lab: Composite Flowers

In this video, you’ll investigate composite flowers such as sunflowers, daisies and chrysanthemums, which appear to be a single flower but are actually many small flowers grouped together in an inflorescence. You’ll distinguish between ray flowers and disk flowers and examine how these specialized structures work together to attract pollinators and support reproduction.

In this activity, you will:
✅ Identify ray flowers and disk flowers in composite inflorescences
✅ Examine symmetry differences between ray and disk flowers
✅ Observe fused petals and reproductive structures in disk flowers
✅ Analyze how composite flowers increase pollination efficiency

Key takeaway: What appears to be a single flower in many Asteraceae species is actually a coordinated group of flowers that improves pollinator attraction and reproductive success.
