Which of the following statements concerning complex multicellular organisms is true? - plants and animals use bulk transport systems to move gases and nutrients, but fungi and algae do not.-bulk transport systems require specialized organs like a heart to pump nutrients and dissolved gases deep into tissues that are not in contact with the external environment.- bulk transport systems move substances faster than simple diffusion.

The true statement concerning complex multi-cellular organism is Bulk transport systems move substances faster than simple diffusion.

Explanation:

Bulk transport is the mechanism that is used by the cells to transport the large quantity of small and tiny molecules and particles. Bulk transport works on the mechanism of pressure gradient and single diffusion is based on the concentration gradient.

The transportation on single diffusion is due to random motion of molecules but in bulk transport the solute and water is moved together and in a faster pace.
