What is the importance of cells that is why are multicellula

What is the importance of cells, that is, why are multicellular organisms divided into cells? (What are the veolutionary advantages?) Include in your answer a discussion of surface area to volume ratios and cell specialization.

Solution

Cells make up the basic structural and functional unit of life. Multicellular organisms have many types of cells which cumulatively add up to the ability of organisms to perform multiple types of functions owing to differential specialization of the cells. The benefits of having multiple cells can be described as below:

Thus, cellular specialization in multicellular organisms is indeed beneficial and has contributed to evolution of organism.
