$<font colour = "red"><b>$Multicellular organisms form from a single eukaryotic cell, the zygote. Organs and tissues, despite sharing functional responsibilities of the body, are multicellular because they are made up of many cells. Multicellular organisms evolved approximately two billion years after unicellular organisms.

Examples: Amoeba and Paramecium, both unicellular. Algae, or plant-like protists, have characteristics of plant cells. Examples: Chlamydomonas (unicellular), Volvox and kelp (both multicellular).
