Structure and Function of Cells

Identify which of these is NOT a major difference between plant and animal cells.

• Only plant cells have a cell wall.

• Only animal cells have mitochondria.

• Animal cells do NOT contain chloroplasts.

• Plant cells have a large central vacuole.

The mitochondria

• Controls what enters and leaves the cell

• Performs photosynthesis to make food for the cell.

• Contains the chromosomes and is known as the "brain" of the cell.

• Breaks down food to produce energy for the cell.

The cell wall

• Controls what enters and leaves the cell.

• Provides structure and support for the plant cell.

• Is a flexible out layer of the cell.

• Is the transportation system of the cell.

The main function of chloroplasts is:

• To control what enters and leaves the cell.

• To break down food to release energy for the cell.

• To control all activities of the cell.

• To produce food for the cell using the sun's energy.
