[2] One common feature of zoospores is their asymmetrical shape; a result of the ventral grove housing the flagella base.
[2] Others form cysts that vary tremendously in volume (14-4905 cubic micrometers) and shape, each with distinctive hair structures.
1 at right: A zoosporangium is the asexual structure (sporangium) in which the zoospores develop in plants, fungi, or protists (such as the Oomycota).
Developing sporangia of oomycetes go through a process of cleavage in which a protein kinase, in the case of Phytophthora infestans, induces the sporangial cytoplasm to split and release the various zoospores.
[5] Others may utilize species of frogs (such as Bufo marinus and Rana catesbieana) as carriers, allowing extended ranges of travel.
