The Flower
A flower is the reproductive structure of a plant, containing petals, sepals, stamens, and pistils, each playing a role in reproduction.
Core concept
Petals are often colourful, attracting pollinators like bees and butterflies, while sepals protect the flower bud before it opens.
How it works
The stamen, the male reproductive part, consists of an anther (produces pollen) and a filament (supports the anther).
Why it matters
The pistil, the female reproductive part, consists of a stigma (receives pollen), style (connects stigma to ovary), and ovary (contains ovules).
Key detail
Understanding flower structure helps us appreciate how plants reproduce and produce the seeds and fruits we depend on for food.
