Lily flower bud, light micrograph
Lily flower bud. Light micrograph of a section through a young flower bud from a lily (Lilium sp.), showing pollen cells (circles) dividing within the anthers (inner ring). The outer floral envelope consists of an outer and inner whorl of three petals (perianth or tepals). Next are the male stamens arranged in two whorls of three, known as the androecium. The anthers, on the ends of the stamens, have four pollen sacs, within which the diploid sporophyte pollen grains are undergoing meiosis (cell division) to form the haploid gameteophyte. In the centre of the flower are the three fused female carpels, which form the gynaecium. Magnification: x3 when printed 10 centimetres wide

EDITORS COMMENTS
This stunning print captures the intricate beauty of a lily flower bud at a microscopic level. The light micrograph reveals the fascinating structures and processes taking place within this young bud. At the center of the image, we can see three fused female carpels forming the gynaecium, which is surrounded by an outer and inner whorl of three petals known as perianth or tepals. Moving outward, we encounter two whorls of male stamens called androecium, with four pollen sacs on their ends. The highlight of this micrograph lies in the anthers where pollen cells are dividing through meiosis to form haploid gameteophytes. These tiny circles represent diploid sporophyte pollen grains undergoing cell division. The meticulous staining technique used for this image enhances our understanding of plant biology and botany. It allows us to appreciate not only the structural complexity but also provides insights into reproductive structures and processes in angiosperms like lilies. With a magnification factor of x3 when printed 10 centimeters wide, this photograph invites us to explore every detail meticulously captured by Science Photo Library's expert photographers. Whether you have an interest in cytology or simply admire nature's wonders, this print will undoubtedly captivate your imagination with its vibrant colors and intricate patterns.
