Anything composed of more than one cell is considered multicellular. This includes all plants, animals, and most fungi. Here are some examples:

* Animals: Humans, dogs, cats, insects, fish, etc.

* Plants: Trees, flowers, ferns, mosses, etc.

* Fungi: Mushrooms, molds, yeasts, etc.

Let me know if you'd like to explore the differences between multicellular and single-celled organisms (unicellular).
