Physarum Polycephalum, commonly known as the Â“blobÂ”, is a unicellular organism that is neither a plant, mushroom or animal. Though it does not have a neuron, it is capable of learning, eating, growing and moving. A 500-million-year-old blob was recently sent to the International Space Station.
The blob appeared on the Earth some 500 million years back. It is unique as it is made of a single cell consisting of multiple nuclei. It does not grow and reproduce through division and multiplication of cells. This microorganism has more than 720 sex types.
