Q3.
The characteristic of blue-green algae is
Solution
(d) Blue-green algae show prokaryotic cell organization, which is characterized by the presence of DNA without histones (but some basic proteins present) 70 S ribosomes, absence of nuclear membrane and membrane bound organelles. Many species like Nostoc,Anabaena contain heterocyst, which is specialized for nitrogen fixation.
