The correct answer is Chlamydomonas.Key Points

  • Chlamydomonas is a type of haploid unicellular eukaryote cell that has a diameter of approximately 10 μm.
  • Half of its volume is occupied by cup-shaped chloroplasts, which are responsible for photosynthesis.
  • Chlamydomonas is found in freshwater environments and is capable of both sexual and asexual reproduction.
  • It is commonly used as a model organism in genetic and biochemical research.

Additional Information

  • Hydrodictyon is a genus of green algae that forms a net-like structure.
    • It is commonly known as the water net.
