Question

Blue green algae belongs to the Kingdom Protista.
A. True
B. False

Answer 1

- Blue green algae also called cyanobacteria are prokaryotic organisms generally green or bluish in colour. They are an example of photosynthetic bacteria. The kingdom Monera is basically divided into two main groups namely Archaebacteria and Eubacteria which contain different types of bacteria according to their composition and habitat.

Complete step by step answer:
Some points regarding blue green algae as well as kingdom Protista are given as follows :
-Kingdom Protista includes all the single-celled eukaryotic organisms. They have well developed nucleus and specialised cell organelles.
-The members of kingdom Protista have special structures for locomotion like flagella, cilia and pseudopodia.
-On the contrary, the kingdom Monera includes all the prokaryotic organisms which lack features such as in protists.
-The prokaryotic cells are entirely different from eukaryotic ones in having primitive type of cell organelles.
-The members of Monera do not have well defined nuclear boundaries and all the vital activities are performed by a single cell.
-In blue green algae, the genetic material inside is not enclosed in a nuclear membrane and there are no cell bound organelles in cytoplasm.
-Thus, we can conclude that cyanobacteria or blue green algae are monerans and not protists because they are prokaryotic in nature.
Hence, the correct answer is option (B) False.

Note: Blue green algae is another name for cyanobacteria which belongs to the group eubacteria. Blue green Algae are served as food for many aquatic organisms. They can also perform nitrogen fixation (converting atmospheric nitrogen into organic form). The pigment chlorophyll is responsible for green colour and pigment phycocyanin is responsible for blue colour.
