Cells

Mitochondria

Respiration takes place here. Generating energy for cellular activities.

Nucleus

Controls the functions of the cell. Contains the D.N.A

Cytoplasm

Where cellular reactions take place. 

Ribosomes

This is the site of protein synthesis.

Cell membrane

This controls the movement of substances in and out of the cell.

Cell wall

This provides structure and protection for the cell. Present in plant and bacterial cells.

Plasmid

This is an additonal circular piece of DNA that can transfer genetic material from one cell to another.
