✅Explanation:
Cyanobacteria, also known as blue-green algae, are a fascinating group of prokaryotic organisms that play a vital role in various ecosystems. One of their distinguishing features is their lack of flagella. Flagella are whip-like structures that many bacteria use for movement. However, Cyanobacteria have evolved other mechanisms for motility, such as gliding or buoyancy regulation.
