opisthokont

noun /ɒˈpɪsθəʊ̆kɒnt/

Any of very many eukaryotes whose flagellate cells propel themselves with a single posterior flagellum.

Based on a single posterior flagellum (opisthokont), flattened, nondiscoid mitochondrial cristae, a chitinous exoskeleton, storage of glycogen instead of starch, lack of chloroplasts, and the code UGA for tryptophan, not chain termination, in their mitochondria, Cavalier-Smith [54] suggests a common origin of the true fungi with animalia and choanoflagellate protozoa (fig. 1).
