EDITORS COMMENTS
This print showcases the intricate beauty of an orchid petal, captured through a scanning electron microscope. The vibrant colors and delicate details are brought to life in this coloured micrograph, revealing the mesmerizing surface of a Cymbidium sp. orchid petal. Upon closer inspection, one can observe the presence of numerous tiny epidermal hairs or trichomes that adorn the petal's surface. These remarkable structures serve a dual purpose: they act as a protective shield against pests while also reducing water loss through evaporation. In nature's ingenious design, these trichomes play a vital role in safeguarding the plant from potential harm and maintaining its hydration levels. They form an essential defense mechanism against insects and other pests that may pose a threat to the orchid's well-being. Additionally, by minimizing water loss through evaporation, these hairs contribute to preserving moisture within the plant's tissues. The photograph not only highlights the botanical marvels found in flora but also offers insight into biological adaptations for survival. SUSUMU NISHINAGA/SCIENCE PHOTO LIBRARY has masterfully captured this stunning image, inviting us to appreciate both the aesthetic allure and scientific significance of this enchanting flower specimen.
