What is the function of the nucleus in the cell?

The nucleus plays a crucial role in the functioning of a cell by controlling cellular activities and storing DNA. It acts as the command center of the cell, where the genetic material is housed. The DNA within the nucleus contains the instructions for the development, functioning, growth, and reproduction of the organism.

This control over cellular activities is made possible because the nucleus regulates gene expression, essentially determining which proteins are produced and when. This regulation is vital for maintaining homeostasis within the cell and responding to external signals.

While other options relate to important cellular functions, they do not encompass the primary roles attributed to the nucleus. Nutrient storage pertains more to other organelles such as vacuoles, energy production is primarily the function of mitochondria, and waste disposal is managed by lysosomes and other related structures. Thus, the nucleus's function in controlling cellular activities and serving as the repository for genetic information is central to life processes.
