Solution
The correct option is A Blue green algae
Algae are a very large and diverse group of eukaryotic organisms, ranging from the microscopic unicellular Chlorella and the diatoms to giant multicellular kelps, the large brown alga. Diatoms are algae (most commonly known as phytoplanktons) with secondary chloroplasts derived from an endosymbiotic red alga. Yeats is also a eukaryote belonging to the kingdom Fungi. However, the Blue-green algae or Cyanobacteria is the most primitive photosynthetic bacteria (prokaryotic- the absence of well-defined nucleus) cell which is quite small and usually unicellular, though they often grow in colonies large enough to see.
Hence, the correct answer is option A.
