Give two examples of unicellular organisms.

• A. Hydra, Chara
• B. Amoeba, Paramecium
• C. Marchantia, Riccia
• D. None of these

Answer 1

The correct option is B Amoeba, Paramecium

Hydra is a eukaryotic, multicellular organism belonging to the phylum Coelenterata.
Chara is a multicellular plant belonging to the group algae.
Marchantia and Riccia both are simple, primitive, multicellular, bryophytic plants with a well-differentiated plant body.

Amoeba and Paramecium both are protozoans belonging to Kingdom Protista. They are unicellular organisms. Thus, the correct answer is option B.
