Framed Photos from Science Photo Library
Upper surface of a pea leaf
Scanning electron micrograph (coloured green) of the upper surface of a pea leaf, Pisum sativum, with the epidermis (left) stripped off (right) to show the palisade mesophyll layer beneath. The waxy epidermis is studded with open stomata, tiny pores that regulate gaseous exchange between the plant & the atmosphere. The palisade cells are elongated & packed closely together. They contain the chloroplasts, cellular organelles involved in the manufacture of starch from the suns energy, carbon dioxide & water (photosynthesis). During daylight when photosynthetic activity is high the stoma are open, at night or during a water shortage the pores close. Mag: X 100 (35mm). Original Original is B/W print B 745/46M

Chloroplast Photosynthesis Pisum Sativum Stoma
17"x15" (43x38cm) Premium Frame
FSC real wood frame with double mounted 10x8 print. Double mounted with white conservation mountboard. Frame moulding comprises stained composite natural wood veneers (Finger Jointed Pine) 39mm wide by 21mm thick. Archival quality Fujifilm CA photo paper mounted onto 1mm card. Overall outside dimensions are 17x15 inches (431x381mm). Rear features Framing tape to cover staples, 50mm Hanger plate, cork bumpers. Glazed with durable thick 2mm Acrylic to provide a virtually unbreakable glass-like finish. Acrylic Glass is far safer, more flexible and much lighter than typical mineral glass. Moreover, its higher translucency makes it a perfect carrier for photo prints. Acrylic allows a little more light to penetrate the surface than conventional glass and absorbs UV rays so that the image and the picture quality doesn't suffer under direct sunlight even after many years. Easily cleaned with a damp cloth. Please note that, to prevent the paper falling through the mount window and to prevent cropping of the original artwork, the visible print may be slightly smaller to allow the paper to be securely attached to the mount without any white edging showing and to match the aspect ratio of the original artwork.

EDITORS COMMENTS
This print showcases the intricate upper surface of a pea leaf, revealing its hidden secrets under the lens of a scanning electron microscope. The green-colored image highlights the mesmerizing structure and functionality of this vital plant organ. On the left side, we observe the stripped-off epidermis, exposing the underlying palisade mesophyll layer on the right. The waxy epidermis is adorned with numerous open stomata, tiny pores that play a crucial role in regulating gaseous exchange between the plant and its surroundings. These microscopic openings allow for efficient intake of carbon dioxide from the atmosphere while simultaneously releasing oxygen produced during photosynthesis. The palisade cells steal our attention as they stretch elongated and tightly packed together beneath. Within these remarkable cells lie chloroplasts - cellular organelles responsible for harnessing sunlight's energy to convert carbon dioxide and water into starch through photosynthesis. This process fuels growth and sustenance for plants, making them true masters at utilizing solar power. During daylight hours when photosynthetic activity peaks, these stomata remain open to facilitate gas exchange essential for energy production. However, in times of darkness or water scarcity, these pores seal shut to conserve precious resources. With a magnification level of 100 times (35mm), this original black-and-white print captures nature's botanical marvels in exquisite detail – an awe-inspiring testament to life's complexity within even seemingly ordinary elements like leaves from Pisum sativum (pea).
