Carboxysomes in a row

Carboxysomes are small compartments inside photosynthetic bacteria where the machinery for capturing carbon dioxide is concentrated. You can see carboxysomes and their characteristic virus-like shape when you look at slices of these bacteria under an electron microscope: Until recently, no one had looked at carboxysomes under the microscope in cells that were still alive.

Animal cells are made up of many smaller membrane-bound compartments called organelles that perform highly specialized functions necessary for life. Incredibly, several of these organelles have been shown to be evolutionarily related to free-living bacteria, captured and incorporated inside a larger cell billions of years ago in a complex mutually beneficial relationship, known as endosymbiosis…
