• For example, the algae " Euglena " and " Dinobryon " have chloroplasts for photosynthesis, but can also feed on organic matter and are John Hogg argued against the use of " protozoa ", on the grounds that " naturalists are divided in opinion and probably some will ever continue so whether many of these organisms, or living beings, are animals or plants . " As an alternative, he proposed a new kingdom called Primigenum, consisting of both the protozoa and unicellular algae ( protophyta ), which he combined together under the name " Protoctista ".
