Tobacco leaf, SEM C015 / 5171

Tobacco leaf. Coloured environmental scanning electron micrograph (ESEM) of the surface of a tobacco (Nicotiana sp.) leaf. The surface is covered in glandular trichomes (hair-like) that secrete distasteful chemicals to deter pests from feeding on the leaves. Also seen are stomata (light green ovals), pores that are the sight of gaseous exchange in the plant

Deterrent Electron Micrograph Esem Gaseous Exchange Gland Glandular Hairs Stoma Stomata Surface Tobacco Plant Trichome Trichomes

EDITORS COMMENTS
This print captures the intricate beauty of a tobacco leaf at a microscopic level. Taken using an environmental scanning electron microscope (ESEM), the image reveals a vibrant array of colors and textures on the leaf's surface. The main feature that immediately catches the eye is the presence of numerous glandular trichomes, hair-like structures that cover the leaf. These trichomes serve as nature's defense mechanism against pests, secreting distasteful chemicals to deter them from feeding on the leaves. In addition to the trichomes, one can also observe light green ovals scattered across the leaf's surface known as stomata. These tiny pores play a crucial role in gaseous exchange within plants, allowing for carbon dioxide uptake and oxygen release during photosynthesis. The photograph showcases not only the botanical wonders found in nature but also highlights various biological processes occurring within plants. It serves as a reminder of how intricately designed and adaptable plant life is, constantly evolving mechanisms to protect themselves and ensure their survival. Photographed by Thierry Berrod from Mona Lisa Production/Science Photo Library, this stunning print offers viewers an up-close glimpse into nature's remarkable creations while celebrating botany, flora, and biology all in one frame.
