Answers (1)
Diatoms are also known as phytoplanktons with secondary chloroplasts derived from an endosymbiotic red alga. Algae is an eukaryotic organism. It consists of the microscopic unicellular Chlorella and the diatoms to multicellular kelps, the large brown alga. Yeast is a eukaryotic organism belonging to the kingdom of Fungi. Blue-green algae or Cyanobacteria is the most primitive photosynthetic bacteria. These are unicellular and do not contain any well-defined nucleus. They are found in diverse habitats, including freshwater, marine environments, and terrestrial surfaces. They primarily reproduce by binary fission and fragmentation, rather than sexual reproduction.
Hence, the correct answer is a) blue-green algae.
