Which term refers to algae that are unicellular?

• A. Rhodophyta
• B. Unicellular Algae
• C. Stipe
• D. Zooplankton

Answer: (B)

In algae, some organisms are single cells while others form many cells or larger structures. If an alga is one cell performing all life processes, it’s described as unicellular. The term that matches this description is Unicellular Algae, which labels those microscopic, single-celled photosynthetic organisms. The other options describe groups or parts that aren’t about being single-celled: Rhodophyta refers to red algae (often multicellular), the stipe is a stem-like part of some seaweeds, and zooplankton are animal plankton. So, Unicellular Algae is the best fit.
