Brown algae (Phaeophyceae) are characterized by the presence of motile reproductive phase (zoospores) with two lateral flagella. Green algae (Chlorophyceae) reproduce by zoospores with two identical anterior flagella. Xanthophyceae is characterized by the formation of zoospores with paired flagella with unequal length. Cyanophycean reproduce by simple division/fragmentation or nonmotile spores and do not exhibit any motile phase during the life cycle.
