Great mullein hairs, light micrograph
Great mullein hairs. Polarised light micrograph of hair-like structures, known as candelabra trichomes, from a great mullein (Verbascum thapsus) plant. The leaves and stems of the mullein have a dense carpet of candelabra trichomes. The trichomes stop insects and molluscs from being eaten. The trichomes can also slow down transpiration by trapping a layer of water vapour from the stomata. Magnification: x7 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of Great mullein hairs, as seen under a polarised light microscope. The image reveals hair-like structures called candelabra trichomes that densely cover the leaves and stems of the Verbascum thapsus plant. These remarkable trichomes serve multiple purposes in protecting the plant from potential threats. Not only do these unique structures act as a defense mechanism against insects and molluscs, preventing them from consuming the plant, but they also play a role in regulating transpiration. By trapping a layer of water vapor released through stomata, these trichomes slow down the process of water loss. The photograph's blue background adds to its aesthetic appeal while highlighting the structural details of these fascinating botanical features. It offers viewers an opportunity to delve into the world of botany and explore nature's ingenious mechanisms for survival. With a magnification factor of x7 when printed at 10 centimeters wide, this print allows us to appreciate every minute detail present on each candelabra trichome. It serves as a testament to both the power and delicacy found within biological systems. This Science Photo Library print is not just an artistic representation; it is also an educational tool that invites us to marvel at nature's complexity while deepening our understanding of protective adaptations in plants.
