Daisy leaf surface, SEM
Daisy leaf. Coloured scanning electron micrograph (SEM) of the surface of a daisy leaf (family Asteraceae, formerly Compositae). Three stomata (leaf pores) can be seen. Stomata are the site of gaseous exchange in a plant. The opening and closing of the stomata is controlled by semi- circular guard cells, which swell and become turgid to close the openings

Daisy Epidermal Epidermis False Colour Guard Cell Opening Pore Pores Respiratory Stomata Structures Surface Cells False Coloured
EDITORS COMMENTS
This print showcases the intricate beauty of a daisy leaf at a microscopic level. Taken using a scanning electron microscope (SEM), this false-colored image reveals the mesmerizing surface of the leaf from the Asteraceae family, formerly known as Compositae. The vibrant colors highlight various structures and cells that make up this botanical wonder. Three stomata, or leaf pores, are prominently displayed in this image. Stomata play a crucial role in gaseous exchange within plants, allowing them to take in carbon dioxide for photosynthesis while releasing oxygen and water vapor. These vital openings are regulated by semi-circular guard cells that surround them. When these guard cells swell and become turgid, they close the stomatal openings. The detailed view provided by SEM allows us to appreciate the complexity and precision of nature's design on an incredibly small scale. The epidermal layer of the daisy leaf is revealed with astonishing clarity, offering insights into its respiratory system and overall structure. This stunning photograph serves as a reminder of how even seemingly ordinary objects can hold extraordinary secrets when viewed through the lens of science. It celebrates both the aesthetic appeal and scientific significance found within our natural world—a testament to the wonders waiting to be discovered through exploration and research.
