Biology Revision Sheet

1. 📌 Essentials

  • Biology: Study of life, interactions, and cellular structures.
  • Characteristics of Life: Organization, metabolism, growth, reproduction, response.
  • Cell Theory: All organisms are made of cells; cells arise from pre-existing cells.
  • etic Material: DNA is the hereditary molecule, double helix structure.
  • Metabolic Processes: Cellular respiration (energy release) and photosynthesis (energy capture).
  • Levels of Organization: Cell → Tissue → Organ → Organ System → Organism.
  • Taxonomy Hierarchy: Kingdom, Phylum, Class, Order, Family, Genus, Species.
  • Macromolecules: Proteins, carbohydrates, lipids, nucleic acids.
  • Cell Membrane: Lipid bilayer with embedded proteins; controls substance entry/exit.
  • Cell Division: Mitosis for growth/repair; meiosis for reproduction and genetic diversity.
  • Genetic Code: Transcription (DNA to mRNA), translation (mRNA to protein).
  • Enzymes: Catalysts lowering activation energy; specific to substrates.
  • ATP: Main energy currency, produced in mitochondria.
  • Water: Cohesion, surface tension, essential for biological reactions.
  • Genetic Inheritance: Mendel’s laws, dominant/recessive, Punnett squares.
  • Genetic Technologies: PCR, cloning, gene editing.
