7th L1 Living Things, Cells, Viruses, Bacteria

What is the difference between unicellular and multicellular organisms?

• Unicellular do not respond to their environment. Multicellular organisms do respond to stimuli in the environment.

• Unicellular organisms are producers, multicellular are consumers.

• Unicellular organisms perform all functions for life with one cell. Multicellular organisms have many cells that work together to keep them alive

• Unicellular organisms are autotrophs and multicellular are heterotrophs.
