Three processes contribute to this movement – diffusion, … WebThere is neither a circulatory nor respiratory system, with gas and nutrient exchange dependent on diffusion and cell-cell junctions. This necessarily limits the thickness of the body in these organisms, constraining them to be “flat” worms. Most flatworm species are monoecious, and fertilization is typically internal. can chrome wheels be paintedWebGas exchange occurs via a special organ system known as the tracheal system.
