Correlated with the mode of life are the two features character istic of all Sporozoa: (a) They absorb only fluid nutriment, osmotically, and so lack any organs for ingesting and digesting solid food; and (b) they reproduce by sporulation, i.e.
In the Telosporidia (comprising the Gregarines, Coccidia and Haemosporidia), sporulation does not begin until the close of the vegetative or trophic period, i.e.
Until growth has ceased; in the Neosporidia (including the remaining orders) growth and sporulation go on coincidently.
