Overview of NEET 2025 Biology Syllabus

The NEET 2025 Biology syllabus is divided into 10 units, encompassing a wide range of topics from both Botany and Zoology. Here’s a breakdown of the units along with their importance:

1. Diversity in Living World

• Covers concepts such as what constitutes living organisms, biodiversity, classification needs, and taxonomy.

• Includes the five-kingdom classification and salient features of major groups like Monera, Protista, Fungi, plants (Algae, Bryophytes, Pteridophytes, Gymnosperms), and animals (non-chordates and chordates).

2. Structural Organisation in Animals and Plants

• Focuses on the morphology and anatomy of various organisms.

• Discusses plant tissues and the anatomy of flowering plants (roots, stems, leaves) alongside animal tissues and systems (digestive, circulatory).

3. Cell Structure and Function

• Explores prokaryotic and eukaryotic cells, their organelles, and functions.

• Emphasizes cellular processes such as transport mechanisms and cell division.

4. Plant Physiology

• Examines physiological processes in plants including photosynthesis, respiration, transpiration, and plant growth regulators.

5. Human Physiology

• Covers human body systems including digestive, respiratory, circulatory, excretory, nervous, and reproductive systems.

• Discusses diseases related to these systems.

6. Reproduction

• Focuses on sexual and asexual reproduction in plants and animals.

• Discusses reproductive health and related topics.

7. Genetics and Evolution

• Explores Mendelian genetics, molecular genetics (DNA/RNA), genetic disorders, and evolutionary biology concepts.

8. Biology and Human Welfare

• Discusses human health issues, diseases caused by pathogens, nutrition, and health care.

9. Biotechnology and Its Applications

• Covers principles of biotechnology including genetic engineering techniques and their applications in medicine and agriculture.

10. Ecology and Environment

• Focuses on ecological principles, ecosystems, biodiversity conservation, environmental issues, and sustainable practices.

Weightage Distribution

The Biology section consists of 90 questions (45 from Botany and 45 from Zoology) out of a total of 180 questions in the NEET exam. Each question carries four marks with a negative marking scheme for incorrect answers. The weightage distribution for each unit is approximately as follows:

• Diversity in Living World: 10%

• Structural Organisation in Animals and Plants: 8%

• Cell Structure and Function: 8%

• Plant Physiology: 10%

• Human Physiology: 12%

• Reproduction: 8%

• Genetics and Evolution: 12%

• Biology and Human Welfare: 8%

• Biotechnology and Its Applications: 5%

• Ecology and Environment: 10%

Preparation Strategies

1. NCERT Books: Since a significant portion of questions are based on NCERT textbooks, thorough reading and understanding are essential.

2. Practice MCQs: Regularly solving multiple-choice questions helps reinforce concepts and improve speed.

3. Focus on Weightage Topics: Prioritize studying high-weightage topics based on previous years' question trends.

4. Visual Aids: Use diagrams for plant anatomy, human physiology systems, etc., to enhance memory retention.

5. Mock Tests: Take regular mock tests to familiarize yourself with the exam pattern and time management.

6. Revision: Regular revision sessions are crucial to ensure retention of complex concepts over time.

Rising Competition and Preparation Strategy

Every year, brilliant minds across India compete for limited seats in prestigious medical colleges. The competition is fierce, and scoring high marks in your Higher Secondary (HS) examinations alone is not enough. Success in NEET requires a deep understanding of concepts in Biology, Physics, and Chemistry. Building a strong foundation in both HS I and HS II courses is essential to mastering the NEET syllabus.

Exam Pattern and Key Details

NEET 2025 will follow a paper-pencil-based format with significant changes compared to previous years:

• Date & Time: May 4, 2025, from 2:00 PM to 5:00 PM.

• Total Questions: 180 compulsory multiple-choice questions (MCQs).

• Duration: 180 minutes (3 hours).

• Marking Scheme:

  • Each correct answer awards 4 marks.

  • Each incorrect answer deducts 1 mark (negative marking).

  • No marks will be deducted for unattempted questions.

Candidates must carefully select answers to avoid losing marks due to incorrect responses. If a question seems too uncertain, it is better to leave it unattempted.

Preparation Tips

To excel in NEET:

1. Understand the Exam Pattern: Familiarize yourself with the structure and syllabus of NEET, which includes topics from Class 11 and Class 12 CBSE curriculum.
