Why diffusion is insufficient for exchange of gas in higher organism?
Answers
Hlo friend ❤️
● Diffusion is insufficient to meet the oxygen requirement of multicellular organisms like human because the body design of multicellular organism like human is very complex.
● They have specialized cells and tissue for performing various necessary functions of the body.
● So oxygen demand of multicellular organism is quite high. As diffusion is very slow process the oxygen requirements of multicellular organism can not be done by diffusion.
● The cells of the the unicellular organisms are in direct contact with out side environment whereas in multicellular are not.
● So, diffusion is insufficient to meet the oxygen requirements of multicellular organism like human as diffusion
is very slow process.
