Yew Leaf Stomata (SEM)
Yew stomata. Coloured scanning electron micrograph (SEM) of stomata (pores) on the surface of the leaf of an English yew (Taxus baccata). Stomata are pores which regulate gas and water exchange between the leaf and the atmosphere. During the day they open (as seen here) to allow the exchange of gases during photosynthesis, closing at night to prevent water loss. They are opened and closed by two bordering guard cells. Yew is a long-lived poisonous tree which inhabits cool, hilly areas throughout Europe and northern Asia. Magnification x4260 (x1050 at 10cm wide)

EDITORS COMMENTS
This print showcases the intricate beauty of a Yew Leaf Stomata, captured through a scanning electron microscope (SEM). The image reveals the colored surface of an English yew leaf, adorned with numerous stomata or pores. These stomata play a crucial role in regulating gas and water exchange between the leaf and its surroundings. During daylight hours, as depicted in this photograph, these tiny openings open up to facilitate the exchange of gases essential for photosynthesis. However, as night falls, they close tightly to prevent excessive water loss. This opening and closing mechanism is controlled by two neighboring guard cells. The yew tree itself is an evergreen coniferous plant that thrives in cool hilly regions across Europe and northern Asia. Known for its longevity and toxicity, it has adapted well to survive in various environments. With a magnification of x4260 (x1050 at 10cm wide), this SEM image offers us a glimpse into the fascinating world of plant anatomy. It reminds us of nature's intricate design and how even the tiniest structures contribute to life-sustaining processes. Captured by Power and Syred from Science Photo Library, this stunning print serves as both an educational tool for understanding gaseous exchange within plants and as a visually striking piece that highlights the delicate details found within our natural world.
