Question

Why is the process of diffusion is insufficient to meets oxygen requirement in human biengs

Answer 1

in unicellular organisms the body is in direct contact with the environment and so simple diffusion is enough to meet oxygen needs.
But the body of multicellular organisms is not with direct contact with the environment and the volume of body is large so simple diffusion is not sufficient to meet the oxygen needs.

Answer 2

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.
