Most protists are ______, including examples such as amoebas and seaweed.

Most protists are ______, including examples such as amoebas and seaweed.

• A. Multicellular
• B. Single-celled
• C. Photosynthetic
• D. Heterotrophic

Answer: (B)

The main idea is that protists are a highly diverse group mostly made up of single-celled organisms. In protists, one cell handles all the essential life processes, so organisms like amoebas live, feed, move, and reproduce within a single cell. Seaweed shows that there are multicellular protists too, but they are less common compared to the many unicellular forms. So, even though protists include some multicellular examples, most protists are single-celled.
