Question

In Single celled organism diffusion is insufficient to meet all the requirements of food exchange of gases or removal of waste but it is not in case of multicellular organisms explain the reason for this difference

Answer 1

u have missplaced unicellular nd multicellular in d ques.
In single celled organism only 1 cell performs all d functions nd that cell is in the direct contact with environment so here diffusion sufficient nd in muticellular organism there are millions of cells only diffusion is nt sufficient as diffusion is also very slow process nd each cell is nt in contact with d environment. MARK ME AS BRAINLIEST.

Answer 2

Hola! ❤️

● 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.
