Describe the functions of the following components of an animal cell: nucleus, mitochondria, and the cell membrane.

The nucleus is where the genetic information of the cell is stored as DNA; the instructions for the cell's activity. The mitochondria provide energy for the cell through the process of respiration, and the cell membrane controls the movement of substances in and out of the cell, allowing it to be protected and nourished.
