Solution
The correct option is A Both Assertion and
Reason are correct and Reason is the correct explanation for Assertion
Cyanobacteria
are photosynthetic blue green algae with prokaryotic structure. They are
members of monera. They are called blue-green algae because they are aquatic and
photosynthetic. They are green due to presence of chloroplasts. They are Gram
positive photosynthetic prokaryotes which perform oxygenic photosynthesis. They
are one of the most successful autotrophic organisms on earth which have
mastered all types of environments- fresh water, sea water, salt marshes, moist
rocks, tree trunks, moist soils, hot springs, frozen waters. Blue-green algae
may be unicellular, colonial or filamentous. Cells are larger and more
elaborate than bacteria. Heterocyst is present for nitrogen fixation.
