How to use this practice set

Quick recap: about 1.7–1.8 million species are known. Naming follows ICBN (plants) and ICZN (animals) and the binomial system of Linnaeus. The hierarchy runs species → genus → family → order → class → phylum/division → kingdom, and common characters decrease as you go up.

Assertion–Reason questions on The Living World (30)

These assertion–reason living world NEET MCQs follow the exam pattern. Attempting living world NEET MCQs in this format trains you to judge two statements at once. Each question has an Assertion (A) and a Reason (R). Choose:

  1. (a) Both A and R are true and R is the correct explanation of A
  2. (b) Both A and R are true but R is not the correct explanation of A
  3. (c) A is true but R is false
  4. (d) A is false but R is true

Assertion–reason living world NEET MCQs 31–40

Check each statement on its own first; these living world NEET MCQs often have both statements true.

Taxonomic groups are distinct biological entities, not merely morphological aggregates.

Q59.
Assertion (A): The higher the category, the easier it is to determine its relationship to other taxa at the same level.
Reason (R): The higher the category, the fewer the characteristics its members share.

  1. (a) Both A and R are true and R is the correct explanation of A

Common doubts

These are the doubts students most often have when practising living world NEET MCQs.

How many questions come from The Living World in NEET?

Usually 1–2. Binomial rules, taxonomic categories and Table 1.1 are the most common sources, and these living world NEET MCQs cover all three.

Which table from this chapter should I memorise?

Table 1.1, Organisms with their Taxonomic Categories, for man, housefly, mango and wheat. Many living world NEET MCQs ask for one cell of this table.

What is the correct way to write a scientific name?

Write the genus with a capital letter and the specific epithet with a small letter, in italics when printed or separately underlined when handwritten, e.g. Mangifera indica.

How do I solve assertion–reason questions quickly?

Check whether A and R are each true on their own. Only if both are true, ask whether R explains A: if yes choose (a), if not choose (b). This works for every assertion–reason item in these living world NEET MCQs.

Should I read the notes before attempting these living world NEET MCQs?

Yes. Read The Living World NEET notes once, attempt all 90 questions without looking at the answers, then revise the topics you got wrong.

Finished these living world NEET MCQs? Revise the full chapter, including Table 1.1, in our The Living World NEET notes. Come back to these living world NEET MCQs a week later to check what you have retained.
