The Living World NEET Questions with Solutions

Below are the Living World MCQs with answers to help students prepare effectively for the exam. These questions cover important concepts such as taxonomy, nomenclature, biodiversity, and the characteristics of living organisms. 

Practising them regularly can improve conceptual understanding, strengthen problem-solving skills, and help aspirants become familiar with the pattern of questions commonly asked in the NEET Biology examination.

Q 1. An attribute found in plants but not animals is

1. Metabolism

2. Sexual reproduction

3. Autotrophy

4. Asexual reproduction

Answer: 3, Autotrophy

Explanation: Autotrophy is an attribute found in plants but not animals. Autotrophs are organisms that make their food using a process known as photosynthesis, and they do not need any other organism to survive. On the other hand, animals rely on obtaining energy from their environment or from autotrophs, which can be through ingestion, absorption, or photosynthesis.

Q 2. Compared to the genus, which of the following is less general in characters?

1. Family

2. Species

3. phylum

4. Class

Answer: 2, species

Explanation: Species would be less general in characters compared to a genus. Family, phylum, and Class would be more prevalent than genus since they are at higher taxonomic levels and include more species than a single genus.

Q 3. Who is also called the “Darwin of the 20th century”?

1. Lamarck

2. Ernst Mayr

3. Carolus Linnaeus

4. Robert May

Answer: 2, Ernst Mayr

Explanation: Ernst Mayr is also called the “Darwin of the 20th century”. He was a German American biologist known for his work in evolutionary biology, population genetics, and systematics. Mayr's work greatly influenced palaeontologists, ornithologists, and evolutionists alike.

Q 4. According to the Five-Kingdom Classification, Archaea and Nitrogen-Fixing Organisms Belong to Which Kingdom?

1. Monera

2. Protista

3. Fungi

4. Plantae

Answer: 1, Monera

Explanation: If the Five-Kingdom System is followed, the Archaea and nitrogen-fixing organisms would be classified under the kingdom Monera. In the Five-Kingdom Classification System, Monera's kingdom includes prokaryotic microorganisms, such as bacteria and blue-green algae (cyanobacteria).

Archaea, a distinct group of prokaryotes, are classified within the kingdom of Monera. Nitrogen-fixing organisms, which can convert atmospheric nitrogen into a usable form for other microorganisms, can also be found in the kingdom Monera.

Q 5. What are the twin characteristics of growth?

1. increase in mass

2. increase in number

3. Both 1 and 2

4. none of the above

Answer: 3, Both 1 and 2

Explanation: Growth is an organism's increasing size, mass, or number. It can be achieved through increased cell production and increased cell size. Therefore, both increases in abundance and number are the twin characteristics of growth.

Q 6. Growth in living organisms is from

1. outside

2. inside

3. both 1 and 2

4. none of the above

Answer: 2, inside

Explanation: Growth in living organisms is primarily from the inside. Cells within an organism divide and multiply, leading to an increase in the number of cells. This internal cell pision and proliferation result in the overall growth of the organism.

The growth process involves the synthesis of new cellular components, such as proteins, nucleic acids, and lipids, which contribute to the increase in size and mass of the organism.

Q 7. In a taxonomic hierarchy, family is interpolated between

1. kingdom and class

2. class and order

3. order and genus

4. class and genus

Answer: 3, order and genus

Explanation: The family is interpolated between the order and genus in a taxonomic hierarchy. From broader to more specific categories, the hierarchical sequence typically goes kingdom, phylum, class, order, family, genus, and species.

Q 8. Growth cannot be taken as a defining property or feature of living organisms because

1. All living organisms do not show growth

2. Non-living things grow from inside

3. Non-living things also grow

4. Some living organisms do not show the process of reproduction

Answer: 1, all living organisms do not show growth

Explanation: Although growth is a characteristic of living organisms, it is not considered a defining property because some non-living objects, such as crystals, also exhibit growth through external accumulation. In living organisms, however, growth occurs from within through cell division. 

Q 9. Growth is synonymous with reproduction for which of the following organisms?

1. unicellular algae

2. amoeba

3. bacteria

4. all of the above

Answer: 4, all of the above

Explanation: Unicellular algae, Amoeba, and bacteria reproduce by cell division. In these organisms, growth and reproduction occur simultaneously, making growth synonymous with reproduction. 

Q 10. Which of the following organisms multiply by fragmentation?

1. fungi

2. filamentous algae

3. planaria

4. all of the above

Answer: 4, all of the above

Explanation: Fungi, filamentous algae, and planaria are all organisms that multiply via fragmentation. Living World gives you an in-depth look at how these organisms reproduce and explains why fragmentation is an important part of their lifecycle.

Q 11. An actual species comprises a population

1. Interbreeding

2. sharing the same niche

3. Reproductively isolated

4. Feeding over the same food

Answer: 3, reproductively isolated

Explanation: An actual species consists of populations that are reproductively isolated from other species but are capable of interbreeding among themselves to produce fertile offspring. 

Q 12. Living organisms can be unexceptionally distinguished from nonliving things based on their ability for

1. responsiveness to touch

2. reproduction

3. interaction with the environment and progressive evolution

4. growth and movement

Answer: 3, Interaction with the environment and progressive evolution

Explanation: The ability to interact with the environment and progressive evolution is the most appropriate basis for distinguishing living organisms from nonliving things.

While living organisms exhibit responsiveness to touch, reproduction, growth, and movement, these characteristics can also be observed in certain nonliving things or processes. For example, some nonliving things can respond to touch due to physical or chemical properties, and certain crystals can grow or move under specific conditions. 

However, the ability to interact with the environment and progressive evolution is unique to living organisms. Living organisms can actively interact with their surroundings, respond to stimuli, and adapt to environmental changes through metabolism and homeostasis. They also can undergo progressive evolution, which involves genetic changes and adaptations over time, leading to the personification and development of new species.
