Which of the following is considered unicellular green algae?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Chlamydomonas.
The correct answer is Chlamydomonas. It is a unicellular green alga belonging to the division Chlorophyta. Chlamydomonas is found mostly in freshwater habitats and is capable of both autotrophic and heterotrophic modes of nutrition. It has two flagella for movement and contains chloroplasts for photosynthesis. In contrast, Oedogonium and Cladophora are filamentous green algae, while Chlorophyta is the broader division that includes various green algae. Thus, Chlamydomonas is specifically regarded as unicellular green algae.
