Answers
Answer:
→ Blue Green Algae also called as Cyanobacteria are one of the most successful organisms on this planet. They are gram-negative (do not take up gram stain) and photosynthetic microorganism. They have successfully survived for over 3 billion years on our planet earth. Initially, they were classified Plantae due to their ability to photosynthesis, but later they were moved to the Monera Kingdom.
Monera are prokaryotic unicellular bacteria whose genetic material is dispersed loosely in the cell. On the other hand, the genetic material of plants and other eukaryotes is held in the cell nucleus. Therefore, blue green algae are placed in Kingdom Monera and not inKingdom Plantae.
Answer:
Monera are prokaryotic unicellular bacteria which does not contain well defined nucleus. The DNA is naked meaning it is not enclosed within nuclear membrane. Their genetic material is dispersed loosely in the cell. Hence, blue green algae are included under Kingdom Monera and not under Kingdom Plantae.
