Characteristics and Distribution of Bacteria — NEET Biology
📚 Practice ConceptBacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms. Bacteria occur almost everywhere. Hundreds of bacteria are present in a handful of soil. They also live in extreme habitats such as hot springs, deserts, snow and deep oceans where very few other life forms can survive. Many of them live in or on other organisms as parasites.
Assertion (A): Bacteria are the sole members of the Kingdom Monera. Reason (R): Bacteria are the most abundant micro-organisms in nature.
View solution & NCERT explanation
Correct answer: B — If both assertion and reason are true but reason is not the correct explanation of the assertion.
Both statements are true from NCERT. NCERT states “Bacteria are the sole members of the Kingdom Monera” (Assertion true) and “They are the most abundant micro-organisms” (Reason true). However, the Reason doesn’t explain WHY bacteria are the sole members of Monera - it provides information about their abundance, which is a separate ecological fact. Both are true but the relationship is not explanatory.
