What is the function of the nucleus in a cell?

It contains the cell's DNA and controls activities. It releases energy from glucose during respiration (ATP production). It conducts photosynthesis. It stores water.

Correct Answer:

It releases energy from glucose during respiration (ATP production).

Explanation:

The nucleus is the cell's control center. It houses the DNA that contains the genetic instructions for making proteins. By regulating gene expression, it tells the cell which proteins to produce and when, guiding growth, metabolism, and division. While energy production from glucose happens in the mitochondria and ATP is generated there, and photosynthesis occurs in chloroplasts, the nucleus provides the instructions that determine which proteins are made to drive all these activities. Water storage, on the other hand, is handled by vacuoles.
