Species Concept Variations — NEET Biology
📚 Practice ConceptTry to collect all the currently accepted meanings for the word 'species'. Discuss with your teacher the meaning of species in case of higher plants and animals on one hand, and bacteria on the other hand.
Assertion (A): The concept of species is absolute and applies identically to bacteria, plants, and animals. Reason (R): All organisms of a species have exactly the same morphology
View solution & NCERT explanation
Correct answer: D — A and R both are false
The species concept is context-dependent—bacteria reproduce asexually and require molecular criteria, unlike higher organisms. Morphological identity alone is insufficient. Within a species, individuals have morphological differences in terms of height, weight etc.
