Cell Structure and Function One Shot for NEET 2026

The Cell Structure and Function One Shot session conducted by Dr. Vipin Kumar Sharma is a high-impact revision class designed for NEET 2026 aspirants. The session is structured into three core chapters:

• Cell: The Unit of Life

• Cell Cycle and Cell Division

• Biomolecules

The class focuses on NCERT clarity, concept building, and exam-oriented MCQs, making it ideal for last-minute revision and strengthening fundamentals.

Cell: The Unit of Life – Core Concepts

Understand the basic structure, types, and importance of cells for NEET preparation.

What is a Cell?

• A cell is the structural and functional unit of life

• Every living organism must have at least one complete cell

Types of Organisms:

• Unicellular: Amoeba, bacteria

• Multicellular: Humans, plants (trillions of cells, ~200 types)

Cells perform both structural and physiological functions, making them the foundation of life.

Cell Theory & Discovery

Learn the origin of cell biology through key scientists and foundational principles.

Important Scientists:

• Robert Hooke – Discovered dead cells (1665)

• Anton van Leeuwenhoek – Observed living cells

• Robert Brown – Discovered nucleus

• Rudolf Virchow – “Cells arise from pre-existing cells”

Exception: Viruses are not considered living cells.

Prokaryotic vs Eukaryotic Cells (Exam Favourite)

Differentiate between prokaryotic and eukaryotic cells for concept clarity and MCQs.

Universal Fact: All cells have plasma membrane & cytoplasm

Prokaryotic Cell Structures

Explore surface structures and functions of prokaryotic cells for exam-based understanding.

• Flagella: Movement

• Pili: DNA transfer

• Fimbriae: Attachment

• Capsule: Protection

• Inclusion Bodies: Storage

Gram Staining:

• Gram + → Purple (thick wall)

• Gram – → Pink (thin wall)

Eukaryotic Cell & Organelles

Key organelles include:

• Mitochondria → ATP production

• Chloroplast → Photosynthesis

• Lysosome → Digestion

• Endoplasmic Reticulum & Golgi → Transport & packaging

Mitochondria & chloroplast have own DNA (endosymbiotic theory)

Enzymes & Metabolism

• Enzymes = Biological catalysts

• Increase reaction speed up to 10⁸–10¹⁰ times

• Work via:

• Lock & Key model

• Induced Fit model

Types of Reactions:

• Catabolic → Breakdown (energy release)

• Anabolic → Synthesis (energy required)

Inhibitors:

• Competitive

• Non-competitive

Biomolecules – Complete Breakdown

Revise all major biomolecules and their structure-function relationship for NEET.

1. Proteins

• Made of amino acids

• Levels: Primary → Quaternary

2. Carbohydrates

• Monosaccharides → Polysaccharides

• Example: Glucose, Starch, Cellulose

3. Lipids

• Fats, phospholipids, steroids

• Saturated vs Unsaturated

4. Nucleic Acids

• DNA & RNA

• Built from nucleotides

All biomolecules contain: C, H, O, N, S, P

Cell Cycle & Cell Division

Understand cell cycle phases and division types for high-weightage NEET topics.

Cell Cycle Phases:

• G1 → Growth

• S → DNA replication

• G2 → Preparation

• M Phase → Division

Types of Division:

• Mitosis → 2 identical cells

• Meiosis → 4 haploid gametes

Important concept: PMAT (Prophase, Metaphase, Anaphase, Telophase)

Key Takeaways for NEET 2026

Quickly revise the most important points to boost your NEET score.

• Cell is the basic unit of life

• Clear difference between prokaryotic & eukaryotic cells

• Enzymes are highly specific & regulated

• Biomolecules form the basis of all life processes

Cell cycle ensures growth, repair & reproduction
