Which one of the following best defines differentiation?
A)the process of gradual structural and functional specialization of daughter cells
B)cell growth
C)fertilization of ovum by sperm
D)maintenance of homeostasis at cellular level
E)coordinated action of different cells

Accepted Answer

Differentiation refers to the process through which unspecialized cells or tissues undergo structural and functional changes to develop more specialized characteristics. This process leads to the formation of different cell types with specific functions. Gradual structural and functional specialization of daughter cells best defines differentiation.
