Chloroplasts in protoplast of tobacco
False-colour transmission electron micrograph of chloroplasts in a protoplast from a tobacco leaf, Nicotiana tabacum, (cultivar Xanthi). A protoplast is a single intact cell which has been chemically treated to breakdown the outer cellulose wall (missing here). This protoplast is sectioned to show the organelles within. The numerous green bodies are chloroplasts, where the process of photosynthesis occurs. The granular body (blue, red) is the nucleus and the eyespot within it is the nucleolus, where the genetic information of the cell is housed. The orange, heart-shaped structure is a vacuole.

EDITORS COMMENTS
This print showcases the intricate world of chloroplasts within a protoplast from a tobacco leaf. The false-colour transmission electron micrograph reveals the hidden beauty and complexity of this single intact cell, which has undergone chemical treatment to remove its outer cellulose wall. The green bodies scattered throughout the image are none other than chloroplasts, the powerhouses where photosynthesis takes place. These vital organelles play a crucial role in converting sunlight into energy for the plant. Amidst this vibrant sea of chloroplasts lies a granular body in shades of blue and red – the nucleus. Within it resides an intriguing eyespot known as the nucleolus, housing all genetic information essential to cellular function. Drawing attention with its orange hue is a heart-shaped structure called a vacuole. This distinct feature serves various functions such as storage, waste disposal, and maintaining turgor pressure within plant cells. With magnification at x1680 and presented in 6x4.5cm size, this stunning photograph offers us an up-close glimpse into the fascinating world of botany and cellular biology. It highlights not only the intricate structures within plants but also emphasizes their importance in sustaining life on our planet. Captured by Science Photo Library's talented photographers, this image represents botanical science at its finest – revealing nature's wonders through advanced technology and scientific exploration.
