A zoospore is an asexual spore that moves by using a flagellum.
These spores, also known as swarm spores, are produced by various protists, bacteria, and fungi in order to reproduce.
Zoospores can have one or more unique forms of flagella, including tinsel or "decorated" flagella and whiplash in various combinations.
Phycomycetes
The Class Phycomycetes is sometimes known as 'algal fungus' because the structure of their filamentous vegetative body and mechanisms of reproduction are similar to those of certain green algae.
Bread mold (Rhizopus), water mold (Saprolegnia), 'white rust' of mustards (Albugo), and 'downy mildews' are examples of common fungi (Peronospora).
Phycomycetes are found in watery environments, rotting wood in moist and humid areas, and as obligatory parasites on plants. They are known as algal fungi.
Phycomycetesfungi reproduce asexually by zoospores (motile) or aplanospores (non-motile).
