Question

A new microorganism has been isolated from hot springs in Yellowstone National Park. It consists of single cells, which appear to lack a nucleus. Chemical analysis shows the presence of both DNA and RNA in the cytoplasm and peptidoglycan in the cell wall. In which of the following groups will this organism be classified?a. Fungi

b. Bacteria
c. Archaea
d. Protists
e. Plants

Answer 1

b. Bacteria

Step-by-step explanation:

Bacterias have following characteristics :

• Simplest organisms with a very small size.
• Lack membrane bound organelles
• Unicellular
• Lack nucleus and contain genetic information in a circular loop called plasmid.
• Cell wall contains peptidoglycan
• Contains both DNA and RNA.

Hence option b) Bacteria is the right option,

It cannot be fungi because their cell wals contain chitin. It cannot be arcahe, protists or plants because all of them have a nucleus.

Answer 2

Answer: B- Bacteria

Explanation: Bacteria are infinitesimal organisms that have single cells that grow in different atmospheres. They have an easily understood inside arrangement. Their cells are normally surrounded by two shielding coverings which are an external cell continuous vertical structure and a cell pliable sheet-like structure acting as a boundary inside. However, some bacteria do have a third shielding sheet furthest from the center named the capsule.
