Chloroplasts from leaf of Coleus
False-colour transmission electron micrograph of a green chloroplast from a variegated leaf of the plant Coleus blumei. Chloroplasts are the sites of photosynthesis in plants & green algae. Chlorophyll pigments, stimulated by light, initiate a chemical reaction, which leads to the formation of sugar from carbon dioxide. Chloroplasts are usually lens-shaped & bound by two membranes; the inner one is folded into a series of stacks called grana (green, threadlike). Chlorophyll pigments are stored on the grana. The large pink region in the chloroplast is a starch grain, a product of photosynthesis. Magnification: x5000 at 6x4.5cm size

EDITORS COMMENTS
This print showcases the intricate beauty of chloroplasts, the powerhouses of photosynthesis in plants and green algae. The false-color transmission electron micrograph captures a green chloroplast from a variegated leaf of the Coleus blumei plant, revealing its fascinating structure and function. Chloroplasts are lens-shaped organelles enclosed by two membranes, with the inner one folded into stacks called grana. These threadlike structures store chlorophyll pigments, which play a crucial role in capturing light energy to initiate photosynthesis. When stimulated by light, these pigments trigger a chemical reaction that converts carbon dioxide into sugar – the life-giving fuel for plants. In this mesmerizing image, we can observe vibrant green grana within the chloroplasts where chlorophyll pigments are stored. Additionally, an eye-catching pink region represents starch grains produced during photosynthesis. With a magnification of x5000 at 6x4.5cm size, this photograph provides us with an up-close view of nature's remarkable machinery at work. It serves as a testament to the wonders of botanical science and highlights how microscopic details contribute to our understanding of plant structure and function. Science Photo Library has once again captured nature's elegance through their lens, offering us an opportunity to appreciate the hidden complexities that sustain life on Earth.
