8D Unicellular Organisms
... Unicellular organisms can only grow to a certain size. If the organism is too big, it cannot get enough of the substances it needs throughout the cell because diffusion is too slow. The tissues in multicellular organisms need to have raw materials transported to them because diffusion would be too s ...
