Question

Why Is diffusion insufficient to meet the oxygen requirement of multicellular organism ?

Answer 1

Answer:No

Explanation:

Because all the cells of the multicellular organisms are not exposed to the external environment thus diffusion cannot be performed by all the cells of the body to meet the oxygen demands.

Hope it helps.

Answer 2

In multicellular organisms like human beings diffusion is insufficient to meet the oxygen requirements of the body because of the following reasons :

• Diffusion is a very very slow process. Thus it can't fulfil the requirements of our body.

• The oxygen in human beings will have to travel last distances inside our body to reach each and every part of the cells.

• The volume of human body is so big that oxygen cannot diffuse into all the internal cells of the human body quickly.

• Also this is the reason for why the respiratory pigments are present in multicellular organisms also.
