It is determined by polygenetic inheritance (NB I think this should read polygenic inheritance)

Explanation:

Polygenic inheritance occurs when multiple genes act together to produce one trait. A good example of this in humans is height. The trait for height is not simple the result of 2 alleles of 1 gene, but 2 (or more) alleles of several genes that all work together to determine height. These traits are sometimes called complex traits or quantitative traits and do not undergo simple Mendelian inheritance.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
