Ultra-detailed Transmission Electron Microscopy (TEM) scan of a single mitochondrion within a cell. The complex internal double membrane structure and folded cristae are sharply defined in a biological grayscale. Jagged, irregularly shaped microplastic fragments, brightly pseudo-colored in fluorescent blue, neon red, and bright yellow, are embedded deeply within the mitochondrial matrix and wedged between the cristae, creating a jarring artificial contrast against the organic structure. Hyper-realistic, 8k resolution, volumetric lighting from within, scientific illustration aesthetic, macro biology.
