In single celled organisms diffusion is sufficient to meet all their requirements of food, exchange of gases or removal of wastes but it is not in case of multicellular organisms. explain the reason for this difference.
Answers
Explanation:
Diffusion is a very slow process. If multicellular organisms used diffusion to meet all requirements of food, exchange of gases or removal of wastes it would take too much of time for carrying even a single particle in the body of the organism and hence diffusion is a process only for unicellular organisms.
Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
