Which best describes a difference between a unicellular organism and a multicellular organism?

• A unicellular organism is a plant and a multicellular organism is a human.
• A unicellular organism has one purpose- to survive.  A multicellular organism has many cells working together to keep the organism alive.
• A multicellular organism is simple and a unicellular organism is complex.
