Question

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

Answer 1

Multicellular organism cell was not contact directly in environment that cause diffusion is insufficient oxygen requirement of Multicellular organism like Human

Answer 2

Heya!

● 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.
