A 3D model of Neuron Cell Structure in Plasm.js. The cell is the structural and functional unit of living organisms. It answers three fundamental requirements: teleonomy, biogenesis and reproduction.nside there is another structure called nucleolus. The nucleolus is a region of the cell nucleus responsible for the synthesis of ribosomal RNA (rRNA). The nucleolus is not an organelle but a dense region of genetic material and protein.
