Zinnia disc floret, SEM

Zinnia disc floret. Coloured scanning electron micrograph (SEM) of a Zinnia sp. flower head disc floret. This floret (true flower) is found in the central (disc) region of the flower head. It is a self-contained reproductive structure, surrounded by leaf-like bracts (green). The anthers (yellow) are the male reproductive parts that produce the pollen. They are fused to form a cylinder around the pistil (brown, female reproductive structure). This will be raised to receive the pollen that will fertilise the plant. Magnification: x20 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of a Zinnia disc floret, captured through a coloured scanning electron micrograph (SEM). The Zinnia sp. flower head disc floret is the focal point of this image, located in the central region known as the disc. Enclosed by leaf-like bracts in vibrant green hues, this self-contained reproductive structure stands out with its unique features. The male reproductive parts, represented by striking yellow anthers, play a crucial role in producing pollen. These anthers are fused together to form a cylinder that surrounds the pistil – the brown female reproductive structure. As nature's ingenious design unfolds, this pistil will be raised to receive pollen and facilitate fertilization for further plant growth. With a magnification of x20 at 6x7cm size, every detail of this floral marvel becomes apparent. From its delicate stigma to the tiny grains of pollen scattered across its surface, each element contributes to the fascinating world of reproduction within plants. This SEM image not only captures the structural intricacies but also highlights how botany intertwines with artistry. It serves as a reminder that even on microscopic scales, nature's wonders never cease to amaze us.
