St. Johns wort seeds, SEM

St. Johns wort seeds. Coloured scanning electron micrograph (SEM) of seeds from a St. Johns wort flower (Hypericum sp.). A seed contains an embryo (a fertilised ovule from which a new plant can grow) and a supply of food. The food is used either while the embryo develops, or during germination. Seed shapes and textures vary widely, affecting how they are dispersed from their parent plant. Dispersal methods include being carried by the wind, or water or on animal coats, or being eaten and deposited in animal droppings

EDITORS COMMENTS
This print showcases the intricate beauty of St. Johns wort seeds, captured through a coloured scanning electron microscope (SEM). Each seed holds within it the potential for new life, containing both an embryo and a nourishing food supply. The development of the embryo relies on this stored food, ensuring its growth or facilitating germination. The diversity in shape and texture among these seeds greatly influences how they disperse from their parent plant. Various methods are employed for dispersal, including wind and water transport, hitching rides on animal coats, or even being consumed by animals and later deposited through droppings. Through this mesmerizing image, we gain insight into the structure and nature of these botanical wonders. It highlights the multiple reproductive parts that contribute to their successful reproduction. Additionally, St. Johns wort is renowned not only for its role in horticulture but also as an herbal medicine with antidepressant properties. Science Photo Library has masterfully captured this moment using advanced imaging techniques such as SEM. This false-coloured micrograph offers a glimpse into the world of plants' reproductive processes while showcasing the intricate beauty hidden within seemingly ordinary seeds like those of St. Johns wort - a testament to nature's remarkable complexity and resilience.
