Multiple choice biology biodiversity and classification monera five kingdoms of living organisms biodiversity and need of classification

What is the reason for the success of monerans?

  1. Eukaryotic nature and rigid cell wall

  2. Absence of nucleus and other membrane bound organelles

  3. Absence of vacuole and microscopic in nature

  4. Rapid rate of cell division and metabolic diversity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Monerans include a wide variety of bacteria. These can survive in extremely hot and salty concentrations, unlike other organisms. They can also divide very fast. They can produce millions of bacteria from one bacteria within minutes. So their rate of survival is very fast.

So, option D is the correct answer.

If organisms on the earth start dying, which group of organisms will be the last to die?

  1. Monera and Plantae

  2. Mycota and Monera

  3. Plantae and Protista

  4. Animalia and Mycota
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Monerans are organisms that can survive extreme conditions like heat and salt concentrations. As a result, they can survive even in hot water springs and volcanoes. They can also reproduce within minutes. So, they can also reproduce within minutes and produce hundreds of organisms like themselves. Mycota are fungi that survive in water bodies and mostly moist and shady locations. They too can survive if they receive moist and shady locations.

So, option B is the correct answer.

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
Reveal answer Fill a bubble to check yourself
E Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

  1. Bacteria and Archaea

  2. Bacteria and Protista

  3. Archaea and Prostista

  4. Archaea and Euarchaea

  5. Euarchaea and Protista
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  1. Monera and Fungi

  2. Fungi and Plantae

  3. Protista and Animalia

  4. Animalia and Monera
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Bacteria having comma-like single curve in their body are

  1. Bacilli

  2. Cocci

  3. Vibrio

  4. Spirilla
Reveal answer Fill a bubble to check yourself
C Correct answer
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 aureus. Bacteria 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.'
