Science

  • Equation:
    6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ (light + chlorophyll)

  • Where: in chloroplasts (mainly leaf cells).

  • Purpose: Converts light energy → chemical energy (glucose).

  • Reactants: Carbon dioxide (air), water (roots)

  • Products: Glucose (used/stored), oxygen (released)

  • Uses of glucose:

    • Respiration (energy)

    • Stored as starch

    • Cellulose (cell walls)

    • Fats and oils (seeds)

    • Proteins (with nitrates)

  • Limiting factors: light intensity, temperature, CO₂ concentration, water, and chlorophyll.

KEVLAR-Kevlar is a strong, lightweight synthetic fiber made from a polymer called poly-para-phenylene terephthalamide. It is formed by polycondensation of p-phenylenediamine (C₆H₄(NH₂)₂) and terephthaloyl chloride (C₆H₄(COCl)₂). It has high strength, is lightweight, heat resistant, tough, and durable. It is used in ropes, cables, tires, sports equipment, and bulletproof vests. TERYLENE (DACRON)-Dacron or Terylene is a strong, wrinkle-free synthetic polyester fiber used in fabrics,

 Genetics (Biology)

DNA & RNA

  • DNA = double helix; carries genetic info; bases pair A–T, C–G
  • RNA = single strand; U instead of T; helps make proteins

Cells & Division

  • Mitosis: 1 cell → 2 identical cells; for growth & repair
  • Meiosis: 1 cell → 4 different cells; makes gametes (sperm/egg)

Chromosomes

  • Humans: 23 pairs = 46 chromosomes
    • 22 pairs = autosomes
    • 1 pair = sex chromosomes (X/Y)
  • Males = XY, Females = XX

Inheritance

  • Dominant allele: shows even if only 1 copy
  • Recessive
