Discuss the advantages and disadvantages of cell specialization. Cell specialization, or rather, cell differentiation, is the process by which unspecialized structures become modified and specialized for the performance of specific functions. This process usually occurs in multicellular organisms, which consist of many groups of specialized cells making up their tissues and organs. Unicellular organisms consist of one general cell under which all activities are housed. In animals, the development of embryos can be divided into three phases; cleavage, gastrulation and organogeny. During cleavage, the zygote undergoes repeated mitotic division to form a hollow ball of cells. In gastrulation, these cells then continue to divide and become rearranged into special layers, called germ layers, within the embryo. It is during the third phase of organogeny that the cells of the germ layers within the enlarging embryo begin to undergo further cell division as well as cell specialization to...
