Here's a breakdown:

* Single-celled protists: The vast majority of protists are single-celled organisms, meaning they are made up of just one cell. These single cells are often complex and can perform all the functions necessary for life. Examples include amoebas, diatoms, and paramecia.

* Multicellular protists: While less common, there are some protists that are multicellular. These organisms are made up of multiple cells that work together. Examples include kelp and some types of algae.

So, while the majority of protists are single-celled, it's important to remember that there are some exceptions!
