Lichen, light micrograph
Lichen. Light micrograph of a section through tissue of a lichen. Lichens are symbiotic associations of a fungus (the mycobiont) with a photosynthetic partner (the photobiont). Here, cyanobacteria (formerly known as blue-green algae) are seen as dark red dots within a loose mass of fungal hyphae (green). The fungus benefits from photosynthetic activity of the bacteria and the bacteria may take advantage of the protection it obtains from drought and intense light. Lichens are slow growing organisms and colonise rocks, tree trunks and soil. Magnification: x150 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate world of lichens, a fascinating example of symbiotic relationships in nature. The image, captured under a light microscope, reveals a section through the tissue of a lichen. Lichens are unique organisms formed by the mutualistic association between a fungus (the mycobiont) and a photosynthetic partner (the photobiont). In this particular specimen, cyanobacteria – previously known as blue-green algae – appear as dark red dots within a loose mass of fungal hyphae colored in green. The photograph beautifully illustrates how these two distinct organisms work together for their mutual benefit. The fungus benefits from the photosynthetic activity provided by the bacteria, while the bacteria find protection from drought and intense light within the structure created by the fungus. This collaboration allows lichens to colonize various environments such as rocks, tree trunks, and soil. With its magnification at x150 when printed at 10 centimeters wide, this micrograph offers us an up-close look into an often overlooked world. It highlights not only the beauty but also the complexity of biological interactions that occur on even smaller scales than our eyes can perceive alone. This stunning print is brought to you by Science Photo Library – your gateway to exploring diverse aspects of biology including botany, bacteriology, microbiology, and more.
