NCERT Based MCQ for NEET Biology

Why NCERT Based MCQs are Important for NEET Biology Preparation?

NEET strictly follows the NCERT syllabus, and the examiners commonly set questions using the same paragraphs and diagrams in these textbooks.

• For example, definitions like "Mitosis is a type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell" are set as they are from NCERT.

• It has been seen from a recent NEET exam analysis that around 90% of Biology questions were NCERT-based content.

• Genetics and Human Physiology are some of the repeating topics each year, and it highlights why more importance needs to be laid on NCERT rather than other books.

NCERT Based MCQ for NEET Biology 2026

Chapter-wise NCERT Based 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 100 most important NEET biology questions improves accuracy and makes revision faster.

NCERT Class 11 Biology MCQs

Class 11 Biology forms the base for many NEET 2026 concepts. NCERT-based MCQs from this section test fundamentals and clear the basics. Practising them regularly builds a strong foundation for higher-level topics.

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 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

Class 12 Biology carries high weightage in NEET. NCERT-based MCQs from this section focus on advanced concepts and frequently asked topics. Solving them helps students revise important chapters and score better in the exam.

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

Chapter: Evolution

Choose the correct sequence of human evolution from the options given below:

Option 1) D A C B

Option 2) B A D C

Option 3) C B D A

Option 4) A B C D

Solution:

The right sequence of human evolution is Homo habilis, then Homo erectus, then Homo neanderthalensis, and finally Homo sapiens. Homo habilis was the first human who used tools, while Homo erectus demonstrated a more efficient gait and a larger brain. Neanderthals were contemporary with early modern humans, and they represent the last stage of this evolutionary process, characterized by the highest level of cognitive ability.

Hence, the correct answer is Option 4)A-D-C-B

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 efficient. 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 MCQ for NEET Biology

The NEET biology syllabus 2026 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.

The data is from the past 5 years, and the chapters transport in plants, strategies for enhancement in food production, digestion and absorption, reproduction in organisms and mineral nutrition are not a part of the syllabus now.

Best Strategy to Solve NCERT-Based MCQs for NEET 2026

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 year 2018 to 2024 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 2026

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

1. Straight Fact-Based MCQs

These tests recall definitions, words, and mechanisms.

Example:

"What is it that controls the body temperature?"

Answer: The Hypothalamus.

2. Application-Type MCQs

These try to use principles to relate them to practical aspects.

Example:

"What happens when red blood cells are placed in a hypotonic solution?"

Answer: They swell up and burst (hemolysis).

MCQ Types and their preparation

Make your study plan based on question types. Give 30 minutes daily to application-based MCQs.

Common Mistakes and their Solutions

Some of the mistakes students make while appearing for the NEET exam are:

1. Omitting NCERT Diagrams

Most students avoid diagrams, but NEET often includes questions based on them. For example, the structure of a neuron is seen in exams nearly every year.

2. Avoiding NCERT Examples

Examples such as Darwin's finches (Class 12 Evolution chapter) are frequently turned into MCQs.

Knowing about these mistakes early improves efficiency in the exam. For example, a weekly revision plan ensures better retention.
