For example, mitochondria help release energy that the cell can use for other tasks, and the nucleus contains the genetic information. The cell membrane forms the boundary that controls what enters and leaves the cell. In plant cells, chloroplasts enable photosynthesis and the cell wall provides structure.

Plants use cell walls to provide structure to the plant. Plant cells contain organelles called chloroplasts, while animal cells do not. Chloroplasts allow plants to make the food they need to live using photosynthesis.
