Question

A scientist discovers a new organism with the characteristic features of locomotion and autotrophic nutrition. Which character(s) would help the scientist identify the organism belonging to Protista according to the five kingdom classification?

Answer 1

The scientist can identify the organism as belonging to Kingdom Protista by observing its unicellular and eukaryotic nature. Protists have a well-defined nucleus and membrane-bound organelles. Some protists, such as Euglena, show locomotion using flagella and autotrophic nutrition through photosynthesis.

Thus, the presence of a true nucleus, unicellular organisation, locomotion and autotrophic nutrition helps identify the organism as a protist.
