What is the important of the transport system in organism ?

• Transport oxygen and nutrients to the body cell

• Transport waste products to the body cells

• Transport urea and mineral salts to the body cell

• Transport carbon dioxide and nutrients to the body cells

Why do complex organisms need transport systems ?

• Diffusion does not occur in simple organisms

• Diffusion does not occur in complex organisms

• Simple organisms have a larger surface area to volume ratio

• Complex organisms have a smaller surface area to volume ratio
