NCERT Based MCQ for NEET Biology

Why NCERT-Based MCQs are Important for NEET Biology Preparation?

NCERT-based MCQs will help the aspirants change their passive reading into active recall. After completing a particular chapter, the aspirants may solve the MCQs, which would help them:

• Find out the concepts and facts that they haven’t understood yet.

• Find out if they can recall the information without going through the NCERT.

• Practice statement-based and application-based questions.

• Revise all the diagrams, tables, and examples.

• Become accurate before attempting Biology test papers.

• Find out the weaker areas.

Which Parts of NCERT Do NEET Biology Questions Come From? Boxes, Tables, Summaries and Diagrams

NEET Biology questions are not limited to the main paragraphs of NCERT textbooks. Questions can also be framed from introductions, examples, tables, diagrams, captions, summaries and other textbook details. Therefore, reading only highlighted lines or memorising selected definitions may leave gaps in preparation.

The following NCERT sections deserve attention:

For example:

• Tables: In classification chapters, tables can help frame questions about differences between groups, their characteristics and examples.

• Diagrams: Questions can test the identification of parts of a cell, flower or human organ system using NCERT illustrations.

• Figure captions: Captions can provide details about a biological process or structure that may be used to frame a question.

• Summaries and examples: Important terms, examples and concepts mentioned in chapter summaries can be converted into direct or statement-based MCQs.

Students should read the textbook line by line and then practise questions from the same chapter. The NCERT line-by-line Biology preparation resource can be used for more detailed textbook-based revision.

Types of NEET Biology MCQs Based on NCERT

NEET Biology questions can test direct recall as well as conceptual understanding. Students should practise different formats instead of focusing only on direct questions.

Regular practice of NEET Biology statement-based and assertion-reason MCQs from NCERT can help students become familiar with questions that require careful reading. Candidates should not assume that a statement is correct simply because it contains familiar textbook terms.

NCERT-Based MCQ for NEET Biology 2027

Chapter-wise NCERT-based NEET MCQ for NEET Biology helps students cover the syllabus in an organised way. Each chapter is linked to NCERT concepts, diagrams, and key facts. Practising the top 100 NEET biology questions will help increase accuracy and speed up the revision process.

Ques: Given below are two statements :
Statement I: In the nephron, the descending limb of loop of Henle is impermeable to water and permeable
to electrolytes.
Statement II: The proximal convoluted tubule is lined by simple columnar brush border epithelium and
increases the surface area for reabsorption.
In the light of the above statements, choose the correct answer from the option given below :

Chapter: Excretory Products and Elimination

Option 1) Both Statement I and Statement II are true

Option 2) Both Statement I and Statement II are false

Option 3) Statement I is true but Statement II is false

Option 4) Statement I is false but Statement II is true

Solution: 

The correct answer is option (2) because both statements are false. Statement I is False because it is indeed the descending limb of the loop that is permeable to water and nearly impermeable to electrolytes, which permit water reabsorption. Statement II is false because the surface area is increased in the proximal convoluted tubule by simple cuboidal brush border epithelium.

Hence, the correct answer is Option 2. Both Statement I and Statement II are false

Ques: Auxin is used by gardeners to prepare weed-free lawns. But no damage is caused to the grass as auxin. 

Chapter: Plant Growth and Development

Option 1) Promotes apical dominance

Option 2) Promotes abscission of mature leaves only

Option 3) Does not affect mature monocotyledonous plants

Option 4) Can help in cell division in grasses, to produce growth

Solution: 

Auxin is used by gardeners to prepare weed-free lawns because it is a plant hormone that, when applied in high concentrations, promotes excessive growth in broad-leaved plants (weeds), leading to their rapid death. However, no damage is caused to grass because grasses are typically insensitive to auxins at the concentrations used for weed control. Grass species, being monocots, have different growth regulation mechanisms compared to the broad-leaved dicots, making them less susceptible to the overgrowth effects caused by auxins. This selective action allows the weeds to be eliminated while the grass remains unharmed.

Hence, the correct answer is that option 3 does not affect mature monocotyledonous plants.

NCERT Class 12 Biology MCQs

Biology MCQs for Class 12 comprise concepts like genetics, evolution, reproduction, biotechnology, and ecology. You can use these questions for recall purposes after studying the respective NCERT chapters.

Ques: 

Given below are some stages of human evolution.
Arrange them in the correct sequence. (Past to Recent)

A. Homo habilis

B. Homo sapiens

C. Homo neanderthalensis

D. Homo erectus

Choose the correct sequence from the options given below.

Option 1) C-B-D-A

Option 2) A-D-C-B

Option 3) D-A-C-B

Option 4) B-A-D-C

Answer: Option 2) A-D-C-B

Solution: The correct sequence of human evolution from past to recent is Homo habilis → Homo erectus → Homo neanderthalensis → Homo sapiens. Therefore, the correct sequence is A-D-C-B, which corresponds to Option 2.

Ques: In which ecosystem is the autotroph-fixed energy likely to reach the primary carnivore level in the shortest time?

Chapter: Evolution

Option 1) Temperate deciduous forest

Option 2) Grasslands

Option 3) Ocean

Option 4) Tropical rainforest

Solution: 

Tropical rainforests have very high productivity and biodiversity. Dense vegetation and diverse species make energy flow fast and efficiently. Autotrophs like trees and plants fix large amounts of energy, which quickly passes to herbivores and then to carnivores.

Other ecosystems, such as temperate forests, grasslands, or oceans, have lower productivity or different food webs, so energy transfer takes longer. Thus, in tropical rainforests, autotroph-fixed energy reaches primary carnivores in the shortest time.

Hence, the correct option is 4. Tropical rainforest.

Chapter-Wise Weightage of NCERT-Based MCQs for NEET Biology

The NEET biology syllabus 2027 is divided into two parts: Zoology and Botany. A deep understanding of the NEET biology syllabus is important for aspiring medical students, as it forms a significant portion of the overall examination, determining their eligibility for admission to undergraduate medical courses in India. The weightage of biology chapters in NEET, based on the past 5 years' analysis, enables aspirants to concentrate their efforts on the most important chapters.

Important NEET 2027 NCERT-Based MCQ Books

Choose books based on your preparation stage. Beginners should start with Arihant’s NCERT MCQs, while advanced learners can go for MTG NCERT Exemplar.

Best Strategy to Solve NCERT-Based MCQs for NEET 2027

Here is a step-by-step guide to prepare for NEET Biology:

Step 1: Read NCERT Line-by-Line

• Mark important words (e.g., Glycolysis Pathway, Ecosystem) and write them down in the margins.

• For example, write down "Calvin Cycle takes place in chloroplasts" in the photosynthesis topic.

Step 2: Practice Diagram-Based MCQs

• Redraw such diagrams as the human respiratory system and label them on bits of paper without consulting the textbook.

• This helps with visual memory, which is highly relevant to NEET.

Common Diagram-Based Questions in NEET

Questions on Biology diagrams test both memory and understanding. Practice daily to avoid mistakes.

Step 3: Solve Previous Years’ Papers

Try to solve NEET previous year papers from the years 2018 to 2026 what will help to identify past trends.

For example, 5–6 questions on genetic disorders appear annually.

Types of NCERT-Based MCQs in NEET Biology 2027

Here are some kinds of NCERT-based MCQs in NEET Biology:
