Dahlia tuber, light micrograph
Dahlia tuber. Polarised light micrograph of a section through the tuber of a Dahlia sp. plant, showing inulin crystals. The Dahlia produces root tubers that are mostly made up of scattered vascular bundles. Parenchyma tissue cells store the insoluble polysaccharide inulin as a means of storing energy. When the tubers are immersed in alcohol the inulin crystallises near bundles as spheroid crystals. Magnification: x7, when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a Dahlia tuber, as seen through a polarised light micrograph. The image reveals the inner structure of the tuber, highlighting its unique composition and storage mechanisms. Dahlia plants produce root tubers that consist mainly of scattered vascular bundles surrounded by parenchyma tissue cells. These cells play a crucial role in storing energy in the form of an insoluble polysaccharide called inulin. In this mesmerizing photograph, we witness how alcohol immersion causes the inulin to crystallize near these vascular bundles, forming stunning spheroid crystals. With a magnification of x7 when printed at 10 centimeters wide, every detail is brought to life under the lens of this light microscope. This microscopic view provides valuable insights into the histology and cytology of dicotyledonous plants like Dahlias. The image not only captures the structural intricacies but also serves as a testament to nature's ingenious design for food storage within plant tissues. By studying such biological phenomena, scientists gain deeper knowledge about botany and plant biology. This remarkable print from Science Photo Library invites us into the fascinating world of botanical wonders while showcasing both scientific precision and artistic allure.
