Blütenorgane

Blütenorgane, also known as floral organs, are the specialized structures that make up a flower. These organs are typically arranged in whorls, or concentric circles, on the receptacle, which is the part of the flower stalk where the organs attach. The outermost whorl is usually composed of the calyx, formed by sepals, which are often green and leaf-like, protecting the developing bud. Inside the calyx is the corolla, made up of petals. Petals can vary greatly in color, shape, and size, often serving to attract pollinators.

The reproductive organs are located within the petals. The male reproductive organs are called stamens, each consisting of a filament and an anther, where pollen is produced. The female reproductive organ is the pistil, or carpel, which typically comprises the stigma, style, and ovary. The stigma is the receptive tip where pollen lands, the style is a stalk connecting the stigma to the ovary, and the ovary contains ovules, which develop into seeds after fertilization. Flowers may have all four types of organs, making them complete, or lack one or more, making them incomplete. They can also be bisexual, possessing both stamens and pistils, or unisexual, having only one type of reproductive organ. The arrangement and characteristics of Blütenorgane are crucial for understanding plant reproduction and classification.
