Flagellum :
A flagellum or flagella is a hairy protrusion that provides mobility to a wide spectrum of microbes, including sperm cells of various plants and animals.
Fungi:
- The majority of fungi are decomposers that obtain nutrients from dead or decomposing organic materials (usually plants).
- Because fungi are non-motile, they do not all have flagella.
- Most members of the kingdom Fungi lack flagella at all stages of their life cycle; these structures are completely missing.
- The only exception is chytrids, which produce flagellated gametes.
