Overview of Biology for NEET

Overview of Biology for NEET

• Importance of Biology in NEET:
  • Constitutes 50% of the NEET exam.
  • Covers two years of NCERT syllabus (Class 11 and 12).

Key Areas of Focus

1. Cell Biology:

   • Structure and function of cells.
   • Cell organelles: Mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
   • Cell division: Mitosis and meiosis.

2. Genetics:

   • Mendelian inheritance: Laws of inheritance.
   • Chromosomes and chromosomal theory.
   • Genetic disorders: Down syndrome, Turner syndrome, etc.

3. Evolution:

   • Theories of evolution: Natural selection, speciation.
   • Evidence of evolution: Fossil records, comparative anatomy.

4. Plant Physiology:

   • Photosynthesis: Light and dark reactions.
   • Plant hormones: Auxins, gibberellins, cytokinins.
   • Transport in plants: Xylem and phloem.

5. Human Physiology:

   • Major body systems: Circulatory, respiratory, digestive, excretory, nervous.
   • Homeostasis: Mechanisms of temperature regulation.
   • Diseases & disorders: AIDS, diabetes, heart diseases.

6. Ecology:

   • Ecosystems and their components: Producers, consumers, decomposers.
   • Biogeochemical cycles: Carbon, nitrogen, phosphorus cycles.
   • Biodiversity: Importance and conservation methods.

7. Biotechnology:

   • Genetic engineering: Tools like CRISPR.
   • Applications in medicine: Vaccines, gene therapy.
   • Ethical issues in biotechnology.

Preparation Tips

• NCERT Textbooks: Primary source for theoretical concepts.
• Diagrams: Practice labeling diagrams (e.g., human skeleton, plant anatomy).
• Previous Year Papers: Review patterns and frequently asked questions.
• Revision: Regularly revise key concepts and terminology.

Exam Strategy

• Time Management: Allocate time per question and avoid spending too long on any one item.
• Practice Mock Tests: Simulate exam conditions to build familiarity and speed.
• Important Topics: Focus on high-weightage topics and those frequently asked.
