• Yeast is an example of a unicellular fungus, but in general, fungi are classified as multicellular organisms.

Information Booster:

• Unicellular organisms are made up of only one cell, which performs all necessary life functions like reproduction, respiration, and metabolism.
• Examples include bacteria, protozoa (e.g., Paramecium), and some algae (e.g., Chlamydomonas).

Additional Knowledge:

• Paramecium is a unicellular protozoan that moves using cilia.
• Bacteria are prokaryotic unicellular organisms with no nucleus.
• Chlamydomonas is a unicellular green algae that performs photosynthesis.
