A cucumber flower diagram illustrates the intricate anatomy of both male and female flowers. The male flower comprises stamens with filaments, anthers, and pollen grains essential for fertilization. The female flower features a pistil containing a stigma, style, ovary, and ovules. Both flowers share structures like petals, sepals, and nectar, which attract pollinators and protect reproductive organs. Understanding flower anatomy is crucial for plant reproduction, ecosystem balance, and pollination adaptations.
