False colour SEM of a brassica seedling
False-colour scanning electron micrograph (SEM) of a seedling of the cabbage plant Golden Acre, a brassica. The picture clearly shows the seed (green), the split seed coat or testa (orange), & the root covered with root hairs. Root hairs are short-lived, delicate structures. Roots grow from the tip, & new hairs are continually produced from a region just behind it. The process is clearly visible here: near the root tip, the hairs are young & short; further away they are longer. Magnification: x6 at 6x4.5cm size

EDITORS COMMENTS
This false-colour scanning electron micrograph (SEM) print showcases a remarkable view of a brassica seedling, specifically the cabbage plant Golden Acre. The intricate details captured in this image offer an insight into the early stages of plant development. The vibrant green hue represents the seed itself, while the striking orange coloration depicts the split seed coat or testa. This outer layer acts as protection for the delicate embryo within and eventually disintegrates as growth progresses. One cannot help but be fascinated by the root system displayed here, adorned with numerous root hairs that play a crucial role in nutrient absorption from soil. These short-lived structures are visible throughout, showcasing their delicate nature. Roots grow from their tips, and this photograph beautifully captures this process in action. As we move closer to the tip, we witness young and short root hairs gradually transforming into longer ones further away. It is truly mesmerizing to observe how new hairs continually emerge just behind the growing tip. With a magnification of x6 at 6x4.5cm size, every minute detail is brought to life on this print from Science Photo Library. This extraordinary visual representation serves as a testament to both its scientific significance and artistic beauty – an exquisite fusion of structure and nature within botany's realm.
