Passage: Myxospores, which develop from sporogonic cell stages inside fish hosts, are lenticular.  They have a diameter of about 10  micrometers and are made of six cells.  Two of these cells form polar capsules, two merge to form a binucleate sporoplasm, and two form protective valves.  Myxospores are infective to oligochaetes, and are found among the remains of digested fish cartilage.  They are often difficult to distinguish from related species because of morphological similarities across genera.  Though M. cerebralis is the only myxosporean ever found in salmonid cartilage, other visually similar species may be present in the skin, nervous system, or muscle.

Question: What are the functions of the six cells that make up a Myxospore?
Two of these cells form polar capsules, two merge to form a binucleate sporoplasm, and two form protective valves
