Which term describes the process of cell formation and specialization as organisms develop?

The correct answer is the term that signifies the process of cell formation and specialization as organisms progress through their life cycle. Development is a comprehensive term that encompasses the stages of early growth, differentiation, and maturation that an organism undergoes from a single cell to a complex structure. During development, cells undergo specific changes that enable them to fulfill distinct roles in an organism's anatomy and physiology. This process includes cell division, differentiation, and the formation of specialized tissues and organs.

In contrast, growth typically refers to the increase in size and mass of an organism rather than the complex changes that lead to specialization. Reproduction refers to the biological process through which new individuals are created, while mutation pertains to changes in the genetic material that can lead to variations but does not specifically describe the organized process of development in an organism. Thus, development accurately captures the essence of how organisms progress from a single cell to a fully formed individual with specialized functions.
