Which best describes the function of the structures that are labelled P and L?

• Structure P controls what enters and exits the cell, and structure L makes food for the cell.

• Structure P holds all the parts of the cell, and structure L provides rigid support for the cell.

• Structure P makes food for the cell, and structure L stores the genetic instructions for the cell.

• Structure P creates the energy for the cell, and structure L controls what enters and exits the cell.
