JKBOSE Class 11 Biology
The Ultimate 50 Most Important Topics
Session 2025-26
Units I & II: Diversity & Structural Organization
- Five Kingdom Classification: Key features of Monera to Animalia.
- Plant Kingdom: Bryophytes vs Pteridophytes life cycles.
- Floral Families: Solanaceae & Fabaceae formulas. Must Draw
- Animal Tissues: Epithelial & Connective tissue types.
- Muscle Comparison: Striated, Smooth, and Cardiac.
Unit III: Cell Structure & Function
- Mitochondria & Chloroplast: Double membrane structure. Diagram
- Fluid Mosaic Model: Plasma membrane detailed structure.
- Mitosis: Stages and biological significance. Diagram
- Meiosis I: Prophase substages (Pachytene/Diplotene).
Unit IV: Plant Physiology
- Calvin Cycle (C3): Steps, enzymes, and ATP count. Flowchart
- Glycolysis: The EMP pathway steps.
- Krebs Cycle: TCA cycle schematic representation. Flowchart
- Plant Hormones: Functions of Auxins, Gibberellins, and ABA.
Unit V: Human Physiology
- Double Circulation: Human heart path. Diagram
- Urine Formation: Glomerular filtration and Tubular reabsorption.
- Nephron Structure: Function of different segments. Diagram
- Sliding Filament Theory: Mechanism of muscle contraction.
- Neuron Structure: Nerve impulse generation.
Asterisk Classes: Analyst’s Strategy
- The 5-Mark Rule: In Biology, NO diagram = Max 3 marks. Draw first, then explain.
- Table Format: Use tables for all “Differentiate” questions like C3 vs C4 plants.
- Scientific Names: Underline biological names (e.g., Homo sapiens) for better presentation.
