Question

Select correct statement with respect to Monera.

• A. They are all autotrophic prokaryotes
• B. They are all chemoheterotrophs
• C. All monerans have a cell wall
• D. They are prokaryotes with 70S ribosome

Answer 1

The correct option is D They are prokaryotes with 70S ribosome

All bacteria are part of Kingdom Monera. They are prokaryotic organisms with 70S ribosomes. They derive their nutrition autotrophically (produce their own food using inorganic substances) or heterotrophically (depend on other organisms or dead and decaying matter for their nutritional requirements) They can be photosynthetic or chemosynthetic autotrophs. Most bacteria are heterotrophic.
Mycoplasma are monerans that lack a cell wall.
