Class 11–12 Biology Key Concepts (CBSE) — NEET Foundation

NCERT Class 11 and 12 Biology made clear: diversity, cells, physiology, genetics, biotech and ecology

Ghosla Academy · School Academics Team

This course brings together the key ideas of the current NCERT Class 11 and Class 12 Biology books: classification and plant and animal diversity, cell biology and biomolecules, plant and human physiology, reproduction, genetics and molecular biology, evolution and health, biotechnology, and ecology. Every lesson highlights NCERT-level facts, diagrams worth practising and the confusions that commonly cost marks in board papers and NEET. NEET questions follow NCERT very closely, so the course trains you to read the textbook actively, make concept maps and test yourself. Exam patterns, syllabus and dates are decided by NTA and can change, so always check neet.nta.nic.in and cbseacademic.nic.in for the current versions. No course can guarantee a rank or a seat; steady revision and honest self-testing are what improve scores.

What you will be able to do

  • Classify organisms using kingdoms, plant groups and animal phyla with correct features
  • Explain cell structure, biomolecules, enzymes, mitosis and meiosis precisely
  • Describe photosynthesis, respiration, breathing, circulation, excretion and coordination
  • Solve Mendelian, sex-linked and Hardy–Weinberg genetics problems step by step
  • Explain DNA replication, transcription, translation and recombinant DNA techniques
  • Apply ecology and biodiversity concepts to Indian examples and NEET-style questions

What you build

  • Physiology concept map with a 30-question NCERT-line self-test
  • Neighbourhood biodiversity and food-web survey using a phone camera

What you need to start

  • Current NCERT Biology textbooks for Class 11 and Class 12 (rationalised edition)
  • Notebook, coloured pens for diagrams and a smartphone camera for the field project
