Multiple choice biology biodiversity and classification animal classification and its benefits criteria for new system of classification five kingdoms of living organisms

Except cell membranes, cells of which of the following kingdom do not possess cell wall

  1. Plantae

  2. Monera

  3. Fungi

  4. Animalia
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Animal shows different types of body organization.
  • Animals can be radial, asymmetric and bilateral symmetric.
  • Most of the animals are triploblastic.
  • The digestive system is incomplete in some phyla and complete in rest of the phyla.
So, the correct option is 'animalia'.

Choose the correct answers from the alternatives given.
Which one of the following is not a characteristic of organisms in the kingdom Animalia ?

  1. Eukaryotic cells without walls

  2. Multicellularity

  3. Obtaining nutrients by ingestion

  4. Storage of carbohydrates as starch
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Plants store complex carbohydrates as starch and animals store them as glycogen in the muscles and liver. Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles. Animals do not have a cell wall but instead, have the outermost plasma membrane or cell membrane on the exterior and with well-developed organelles enclosed in membranes (eukaryotes) and are also multicellular (being made of more than one cell) and are heterotrophic as animals cannot make their own food. 

So, the correct option is, 'Storage of carbohydrates as starch'.

Golgi apparatus does not occur in

  1. Yeast

  2. Liver cells

  3. Higher plants

  4. Bacteria and blue green algae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Prokaryotes are unicellular organisms. They lack membrane-bound organelles like mitochondria, golgi apparatus. They also lack true nucleus. Instead, they have nucleoid or incipient nucleus. Nucleoid is an undifferetiated, unorganised, fibrillar nucleus without any limiting membrane. They have ribosomes in the cytoplasm. Examples include bacteria like E. coli, blue green algae. 

Thus, the correct answer is 'Bacteria and blue green algae.'

Which of the following is not a moneran?

  1. Spirulina

  2. Nostoc

  3. Oscillatoria

  4. Euglena
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Moneran are prokaryotic unicellular organisms. They lack membrane-bound organelles. They lack true nucleus. They have genetic material without nuclear envelope. The examples of Moneran include bacteria, blue green algae like Nostoc, Spirulina, Oscillatoria. Euglena is an eukaryotic organism

So, the correct answer is 'Euglena'

Prokaryotes are placed in a group known as 

  1. Monera

  2. Pteridophytes

  3. Bryophyta

  4. Angiosperms
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Prokaryotes are placed in a group Monera. These includes bacteria, Cyanobacteria, Eubacteria, etc. They are unicellular organisms. They have cell wall. They lack membrane-bound organelles like mitochondria. They also lack true nucleus. Instead, they have nucleoid, a genetic material without nuclear envelope.

Thus, the correct answer is 'Monera.'

Comma shaped bacteria are

  1. Bacilli

  2. Spirilla

  3. Vibrios

  4. Cocci
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 having spiral shape are called as Spirilla. Examples include Spirillum, Campylobacter.
  • Bacteria having a comma-like single curve in their body are Vibrio. Examples include Vibrio cholerae, Vibrio vulnificus.
  • Bacteria that are round in shape are called as cocci. Examples include Streptococcus pneumoniae, Staphylococcus aureus. 
Thus, the correct answer is 'Vibrios.'

In Whittaker's classification, non-nucleated unicellular organisms$/$ prokaryotes are included under

  1. Plantae

  2. Monera

  3. Protista

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

Whittaker's classification includes five kingdom classification system. The five kingdoms include Monera, Protista, Fungi, Plantae, and Animalia. Monera includes Eubacteria and Archeobacteria. They include non-nucleated unicellular organisms. They are prokaryotes. They have a cell wall. They have no membrane-bound organelles and true nucleus.

Thus, the correct answer is 'Monera.'

Death factor is secreted by 

  1. BGA

  2. Archaebacteria

  3. Fungi

  4. Mycoplasm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cyanobacteria (Blue-green algae or BGA) sometimes reproduce exponentially to form blooms. Blooming cyanobacteria can secrete death factors in such concentrations that they poison and even kill animals and humans. It can also accumulate in other animals such as fish and shellfish and cause poisonings such as shellfish poisoning.

So, the correct answer is 'BGA'.
