How does a multicellular organism overcome the factor that limits the size of unicellular organisms?
Multicellular organisms work together in order to keep this from happening. Large animals have organs such as kidneys, lungs and intestines that increase the surface area available for exchange processes, and a circulatory system to move material and heat energy between the surface and the core of the organism
What is the difference of diffusion and osmosis
Diffusion is the random movement of a substance through a high concentration to a low concentration area. For this to be consider diffusion it must pass through a semi permeable membrane
