13 Important Similarities between Unicellular and Multicellular organisms

Similarities between Unicellular and Multicellular organisms

Unicellular organisms are single celled organisms .  These organisms are  small in size and have simple structures. Unicellular organisms are able to carry out all of the functions necessary for life, such as metabolism, growth, and reproduction, within a single cell. Examples -bacteria, protozoa, and algae.

Multicellular organisms are composed of multiple cells. These organisms have a more complex structure and are larger in size. Multicellular organisms have specialized cells that perform specific functions, such as nerve cells, muscle cells, and skin cells and these  cells work together to carry out the functions necessary for life, such as metabolism, growth, and reproduction. Examples – plants, animals, and fungi.
