Questions Related to monera

Monera is the name of a subkingdom.

  1. True

  2. False


Correct Option: B
Explanation:

The correct answer is 'false'

In the taxonomic classification, Monera is a kingdom not a subkingdom and consists of prokaryotic organisms.

The domain is
I.   Eukaryota
II.  Archaebacteria
III. Eubacteria

  1. I only

  2. II only

  3. III ony

  4. I and III

  5. I, II, and III


Correct Option: E
Explanation:
  • Domain is the broadest taxonomic category and includes one or more kingdoms.
  • Three domains of life are namely Bacteria, Archaea and Eukarya. Domain bacteria include kingdom bacteria, domain Archaea corresponds to kingdom Archaea and domain Eukarya includes kingdoms Protista, Plantae, Fungi, and Animalia.
    So, the correct answer is 'I, II, and III'

A unicellular prokaryote belongs to

  1. Animalia

  2. Eubacteria

  3. Fungi

  4. Plantae

  5. Protista


Correct Option: B
Explanation:

Eubacteria, or "genuine" microbes, are single-celled prokaryotic microorganisms that have a scope of qualities and are found in different conditions all through all parts of the world. A wide range of microscopic organisms falls under this title, with the exception of archaebacteria. Since eubacteria are so normal, it contains one of the three areas of life; the three spaces are Archaea, Bacteria, and Eukarya.

Hence the correct option is B.

Which of the following groups belongs to the alternative eight-kingdom system of classification?

  1. Bacteria and Archaea

  2. Bacteria and Protista

  3. Archaea and Prostista

  4. Archaea and Euarchaea

  5. Euarchaea and Protista


Correct Option: A
Explanation:

The eight kingdom system of classification was given by Tom cavalier smith. His classification completely reversed the Whittaker's five kingdom classification. The eight kingdoms in Cavalier Smith’s classification are Eubacteria, Archaebacteria, Archezoa, Protozoa, Chromista, Plantae, Fungi, and Animalia

The correct answer is A.

Name the category which includes unicellular prokaryotes.

  1. Animalia

  2. Eubacteria

  3. Fungi

  4. Plantae

  5. Protista


Correct Option: B
Explanation:

Among the given options, Animalia, Fungi and Plantae clearly fall under the eukaryotic domain. Protista can be considered as a heterogeneous group of eukaryotes as they consist of a nucleus enveloped in a nuclear membrane. Eubacteria basically refers to the entire bacterial population which will consist of unicellular prokaryotes. 

Select  incorrect  pair _________________.

  1. Porifera-choanocytes

  2. Coelenterata-nematocysts

  3. Annelida - segmentation

  4. Monera - eukaryote


Correct Option: D
Explanation:

Choanocytes or collar cells are the main cell types of kingdom Porifera. Coelenterata (Cnidaria) have nematocysts to catch the prey. Phylum Annelida contains ringworms or segmented worms. Monerans are unicellular prokaryotic organisms.

The correct answer is D. 

Plant decomposers are _______________.

  1. Monera and Fungi

  2. Fungi and Plantae

  3. Protista and Animalia

  4. Animalia and Monera


Correct Option: A
Explanation:
Decomposers are living components mainly the bacteria and fungi that break down the complex compounds of the dead protoplasm of producers and consumers absorb some products and release others.
So, the correct answer is 'Monera and Fungi'

Bacteria having comma-like single curve in their body are

  1. Bacilli

  2. Cocci

  3. Vibrio

  4. Spirilla


Correct Option: C
Explanation:

Bacteria having rod shaped structure are called as Bacilli. Examples include Clostridium tetani, Corynebacterium. Bacteria that are round in shape are called as cocci. Examples include Streptococcus pneumoniae, Staphylococcus aureusBacteria having comma-like single curve in their body are Vibrio. Examples include Vibrio cholerae, Vibrio vulnificus. Bacteria having spiral shape are called as Spirilla. Examples include Spirillum, Campylobacter.

Thus, the correct answer is 'Vibrio.'

Bacillus subtilis are

  1. Hay bacteria

  2. Nitrifying bacteria

  3. Ammonifying bacteria

  4. Intestinal bacteria


Correct Option: A
Explanation:

Bacillus subtilis are also called as hay bacillus. They are gram-positive bacteria. They are commonly found in hay or upper layer of soil. Hence, they are called as hay bacteria. They are also found in the GI tract of ruminants and humans. They are obligate aerobes. 

Thus, the correct answer is 'Hay bacteria.'

Syphilis causing bacterium Treponema pallidum belongs to the group

  1. Rickettsiae

  2. Bacillus

  3. Actinomycetes

  4. Spirillum


Correct Option: D
Explanation:

Treponema pallidum is a motile spirochaete bacterium that causes sexually transmitted disease syphilis.  It is a helically coiled microorganism. It belongs to the group Spirillum. It is a gram-negative bacteria. 

Thus, the correct answer is 'Spirillum'.
