Question

Which one belongs to monera?

• A. Amoeba
• B. Escherichia
• C. Gelidium
• D. Spirogyra.

Answer 1

The Correct Option is B

The question asks us to identify which organism belongs to the kingdom Monera. To answer this, we need to understand the basic characteristics of the organisms listed in the options and the Monera kingdom.

Understanding the Monera Kingdom

The Monera kingdom primarily consists of prokaryotic organisms. Prokaryotes are single-celled organisms that lack a true nucleus and membrane-bound organelles. The two main groups within this kingdom are Bacteria and Archaea. Members of this kingdom reproduce asexually, typically through binary fission.

Analyzing the Options

• Amoeba: Amoebas are unicellular organisms but belong to the kingdom Protista. They are eukaryotic, meaning they have a true nucleus and membrane-bound organelles.
• Escherichia: This refers to the bacterium Escherichia coli (E. coli), which is a well-known prokaryote. E. coli falls under the kingdom Monera.
• Gelidium: Gelidium is a type of red algae, which belongs to the kingdom Protista. These organisms are multicellular and eukaryotic.
• Spirogyra: Spirogyra is a filamentous green alga and is also part of the kingdom Protista. It is eukaryotic.

Conclusion

From the analysis above, we can conclude that Escherichia, specifically Escherichia coli, is a bacterium and belongs to the kingdom Monera. Other options listed are eukaryotes from the Protista kingdom.

Correct Answer

The correct answer is Escherichia.
