Question

Which of the following is not a criterion for the classification of living organisms?

• A. Body design of the organism
• B. Ability to produce one’s own food
• C. Membrane-bound nucleus and cell organelles
• D. Height of the plant

Answer 1

The correct option is D

Height of the plant

The correct option is D.

The explanation for the correct option:

1. Living organisms like plants and animals are classified based on their characteristics and composition.
2. Height is not considered a criterion for the classification of living organisms.

The explanation for the incorrect options:

Option A:

1. In plants, body design like the absence or presence of cell walls is one of the criteria for the classification of living organisms.

Option B:

1. The ability to produce one’s food, that is, mode of nutrition is one of the criteria for the classification of living organisms.
2. There are two modes of nutrition, that is, autotrophic and heterotrophic.
3. The mode of nutrition in which organisms produce their food is autotrophic nutrition like plants, cyanobacteria, etc.
4. The mode of nutrition in which organisms obtain their food from others is a heterotrophic mode of nutrition like humans, animals, etc.

Option C:

1. The presence or absence of a well-defined nucleus with a nuclear membrane and other organelles like lysosome, ribosome, Golgi complex, etc. is one of the essential criteria for the classification of organisms.
2. Organelles are the membrane-bound compositions found within the eukaryotic cells that perform the essential activities.
3. The presence or absence of organelles helps in differentiating prokaryotes from eukaryotes.

Final answer: The height of the plant is not a criterion for the classification of living organisms.
