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

Starting with a bacterium that divides once in half hour, how many bacteria are formed after $24$ hours of growth?

  1. $2^{12}$
  2. $2^{24}$
  3. $2^{48}$
  4. $2^{47}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Since the bacteria divides once in half hour. In one hour number of times it will divide = 2

So, in 24 hours number of times the bacteria will divide = 2*24= 48 times
So, number of bacteria formed after 24 hours = 2$^4$$^8$ 
So, the correct answer is '2$^4$$^8$'.

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 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.

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.'

Bacillus subtilis are

  1. Hay bacteria

  2. Nitrifying bacteria

  3. Ammonifying bacteria

  4. Intestinal bacteria
Reveal answer Fill a bubble to check yourself
A Correct answer
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.'
