Match the organelle to its description.

• Cell Membrane

• Controls all activity in the cell (the brain) and stores DNA

• Mitochondrian

• Proteins are made on these small structures.

• Cytoplasm

• Outer lining the cells.

  Controls what goes

  in and out.

• Ribosomes

• Power plant of the cell. They

  create energy called ATP.

• Nucleus

• The fluid that fills the cell and

  keeps the organelles in place
