Plasma Raspberry

You may be tempted by the glowing plump compartments of this fruity shape, but what looks like a glossy candy coating is really a biochemical unraveling. The electric blues trace the outlines of decaying cell walls in a potato root colonized by mold, and the acidic reds mark the accumulation of anthocyanins as a last-ditch stress response to fight off the invader.
