Why diffusion is insufficient for uptakes?
Answers
Nice question dear ❤️
● 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.

Thanks for asking ❤️
Since diffusion is a very slow process and it will require very large amount of time for oxygen to reach each and every part of the body. That is why diffusion is insufficient to meet the energy requirements of multicellular organisms like humans
