Vedclass · Answer

(B) Multicellular organisms,such as humans,possess complex body designs.They have specialized cells and tissues for performing various necessary functions of the body,such as the intake of food and oxygen.Unlike unicellular organisms,most cells in multicellular organisms are not in direct contact with the outside environment.Therefore,diffusion is a slow process and cannot meet the oxygen requirements of all cells in a complex body.

Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
