. The biology of the protozoa. Protozoa; Protozoa. w imfm*1. Fig. 123.— Polystomellina crispa. A zygote (A) develops into an organism with a microspherie type of shell (B) in which the nucleus divides by mitosis until many nuclei are present which form chromidia. The protoplasm fragments into reproduc- tive bodies or agametes, each having several granules of chromidia (C). Each agamete develops into an adult with a macrospheric type of shell (D, E): when adult these fragment into hundreds of flagellated gametes (F) which fuse in fertilization and so complete the cycle.
