Chloroplast, SEM
Chloroplast. Coloured scanning electron micrograph (SEM) of a section through a plant cell, showing a fractured chloroplast (green). Chloroplasts are the site of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight. The pigment responsible for photosynthesis, chlorophyll, is found on stacks of parallel thylakoids (membranes, brown) called grana

EDITORS COMMENTS
This print showcases the intricate beauty of a chloroplast, captured through a coloured scanning electron microscope (SEM). The image reveals a fractured chloroplast in vibrant green, highlighting its significance as the powerhouse of photosynthesis within plant cells. Chloroplasts play a crucial role in synthesizing carbohydrates from carbon dioxide and water using sunlight. The stacks of parallel thylakoids, seen here in brown membranes called grana, are adorned with the pigment responsible for photosynthesis - chlorophyll. These pigments absorb light energy to initiate the chemical reactions that convert sunlight into usable energy. The false-coloured SEM image provides an extraordinary glimpse into the inner workings of this organelle. It offers us insight into plant anatomy and biology by showcasing various components such as grains, stroma, plastids, and membranous structures. By freezing this fracture sectioned sample and examining it under an electron microscope, scientists have unraveled the complex architecture of chloroplasts. This photograph not only captures their delicate structure but also emphasizes their vital role in sustaining life on Earth through oxygen production and carbohydrate synthesis. Nature enthusiasts and botany lovers will find themselves captivated by this stunning visual representation of one of nature's most essential cellular structures – the chloroplast.
