The nucleus produces energy for the cell.
The nucleus digests waste materials in the cell.
The nucleus helps the cell move.

What do cells use the molecules for once they are inside the cell?
To make energy, build parts of the cell, or help the cell grow and repair itself.
To store waste products permanently.
To destroy the cell membrane.
