Final answer:
Mitosis and differentiation are essential processes for producing and maintaining complex organisms.
Step-by-step explanation:
The subject of the question is Biology. Specifically, the student is asking about the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms. Mitosis is the process of cell division that allows organisms to grow and repair damaged tissues. Differentiation is the process by which cells specialize to perform specific functions in the body, such as forming tissues and organs.
An example of cellular division is when a fertilized egg undergoes a series of mitotic divisions to develop into a complex organism, such as a human. As the cells divide, they differentiate to form various tissues and organs, such as the heart, lungs, and brain.
In summary, cellular division (mitosis) and differentiation play crucial roles in producing and maintaining complex organisms, allowing for growth, repair, and specialized functions.
