Protista
The Kingdom-level grouping known as Protista or Protoctistae consists mainly of microscopic organisms. It is defined by exclusion: its members are neither animals (which develop from a blastula), plants (which develop from an embryo), fungi (which lack
undulipodia and develop from spores), nor prokaryotes. It includes the green algae (Gamophyta and Chlorophyta), red algae (Rhodophyta), brown algae (Phaeophyta), diatoms (Bacillariophyta), and other groups.
Different authorities have differing views on the taxonomy of these organisms.
