French lavender leaf pore, SEM
French lavender leaf pore. Coloured scanning electron micrograph (SEM) of an open stoma (centre, black). Stomata are pores that open and close in order to regulate gas exchange in a plant. A pair of specialized cells known as guard cells (centre, green, oval), control the size of the opening by swelling to close the pore and shrinking to open it. Stomata are found mainly on the underside of leaves. This stoma is on a French lavender (Lavandula dentata) leaf. Magnification: x1889 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a French lavender leaf pore, captured through a scanning electron microscope (SEM). The image reveals an open stoma at its center, appearing as a dark void amidst the vibrant green backdrop. Stomata play a crucial role in regulating gas exchange within plants, allowing them to breathe and maintain their metabolic processes. In this mesmerizing composition, we witness the specialized guard cells (highlighted in oval-shaped green) that control the size of the opening by swelling or shrinking accordingly. The French lavender leaf serves as the canvas for this microscopic marvel, belonging to Lavandula dentata species. Its annual shrub nature and fragrant aroma make it an enchanting addition to any botanical collection. This SEM magnification offers us a closer look at its surface texture and highlights the unique features of plant anatomy. As we delve into this realm of biology and botany, we are reminded of how every living organism possesses its own specialized mechanisms for survival. Through images like these, Science Photo Library continues to provide invaluable insights into our natural world while celebrating both scientific discovery and artistic expression.
