Knowledge Point 01: The Fascinating Classification of Complete and Incomplete Flowers in Nature
Most plant flowers are composed of four parts: sepals, petals, stamens, and pistils. Flowers with all these parts are called complete flowers. And those lacking one or more of these parts are incomplete flowers.
Complete flowers, like rapeseed flowers, have a full structure with each part playing its role in the reproduction process. Sepals protect the inner petals, petals attract insects for pollination, stamens produce pollen, and pistils receive pollen to form seeds. Incomplete flowers, which may lack petals or stamens, still reproduce through other means, demonstrating the resilience and diversity of life.
Knowledge Point 02: The Mystery of Plant Gender: Male Flowers, Female Flowers, and Bisexual Flowers
In the plant kingdom, flowers are not all the same in gender. Flowers with only stamens are male flowers, those with only pistils are female flowers, and those with both stamens and pistils are bisexual flowers.
Male flowers are responsible for producing pollen, while female flowers receive it. Bisexual flowers have both functions, making them more flexible. This gender classification enables plants to more effectively utilize resources during reproduction, increasing the success rate. It also adds more fun and mystery to the plant world.
Knowledge Point 03: Flowering and Fruiting, the Continuation of Plant Life
Plants produce seeds through flowering and fruiting, thereby continuing their life cycle. Flowers are the reproductive organs of plants, and after pollination, the ovary develops into a fruit containing seeds.
The process of flowering and fruiting is a crucial part of the plant life cycle. Flowers attract insects for pollination, and after pollination, the ovary gradually develops into a fruit, which protects the seeds until they mature and scatter to start new life journeys. This process not only showcases the resilience and beauty of plant life but also provides us humans with abundant food and resources.
