o The zoospore resulting from vegetative reproroduction are motile and may often be found swimming around prior to settling on a substratum by means of a holdfast disk(usually quite elaborate) and growing into filament.
o There are a number of species.Mean cell diameter is an unreliable guide to species discrimination as filaments vary in width from one end to the other: however median diameter of 8, 14, 30 and 45 ------m.
