Question

What is the common feature of Gonyaulax, Euglena, Amoeba and Pinnularia?

• A. They show holozoic nutrition
• B. They show autotrophic nutrition
• C. They are unicellular and prokaryotic
• D. They are unicellular and eukaryotic

Answer 1

The correct option is D They are unicellular and eukaryotic

Kingdom Protista includes all the unicellular eukaryotes. They are predominantly aquatic organisms with most of them being marine. They include both autotrophs as well as heterotrophs. Gonyaulax, Euglena, Amoeba and Pinnularia all belong to the kingdom Protista, all are unicellular and eukaryotic organisms. Holozoic nutrition is seen in Amoeba and Euglena. All the mentioned organisms except Amoeba are said to be photosynthetic, so their mode of nutrition is autotrophic.
