Here's a breakdown:
* Cells: The basic building blocks of life. Each cell is a self-contained unit that can carry out its own functions.
* Multicellular: Organisms made up of multiple cells working together. These cells specialize and cooperate to form tissues, organs, and organ systems, allowing for complex life forms.
Examples of multicellular organisms include:
* Animals: Humans, dogs, cats, insects, fish, etc.
* Plants: Trees, flowers, ferns, etc.
* Fungi: Mushrooms, yeasts, molds, etc.
Contrast with Unicellular:
Unicellular organisms are made up of only one cell. Examples include bacteria, amoeba, and yeast (in some cases).
