Focus topics (start here)

Each card is a full micro-lesson: learn → check → apply.

Focus 1

Bioenergetics

Paper 1 · Both

Full notes

Teach it

  • Photosynthesis

    Photosynthesis uses light to convert carbon dioxide and water into glucose.

  • Respiration

    Aerobic respiration releases energy using oxygen.

Key facts

  • Chlorophyll absorbs light for photosynthesis.
  • Respiration happens in mitochondria.
  • Light intensity is the limiting factor at low light.
  • Anaerobic respiration in yeast produces ethanol and carbon dioxide.

Key terms

Aerobic: Reactions that use oxygen.
Anaerobic: Reactions that do not use oxygen.
Limiting factor: The factor that stops the rate increasing.

Quick check

Explain how temperature affects the rate of photosynthesis.

Focus 2

Cell Biology

Paper 1 · Both

Full notes

Teach it

  • Cell Structure and Microscopy

    Know organelles and their functions: nucleus, mitochondria, ribosomes, chloroplasts.

  • Cell Division

    Mitosis produces two identical cells for growth and repair.

Key facts

  • Last-minute priority: organelle functions and transport definitions.
  • Higher SA:V ratio means faster diffusion.
  • Prokaryotic cells (bacteria) are smaller and lack a nucleus.
  • Specialised cells have adaptations that match their function.

Key terms

Diffusion: Net movement of particles from high to low concentration.
Osmosis: Movement of water through a partially permeable membrane.
Mitosis: Cell division producing two identical daughter cells.
Prokaryote: Cell without a nucleus, like bacteria.
Eukaryote: Cell with a nucleus, like plant and animal cells.
Binary fission: Asexual reproduction in bacteria by splitting.

Quick check

Explain why root hair cells are adapted for absorption.

Focus 3

Ecology

Paper 2 · Both

Full notes

Teach it

  • Ecosystems and Food Webs

    Food chains show energy transfer between trophic levels.

  • Cycles and Resources

    Carbon and water cycles move materials through ecosystems.

Key facts

  • Biodiversity is higher in stable, undisturbed ecosystems.
  • Human impacts include pollution, deforestation, and climate change.
  • Quadrats can be used to estimate population size.
  • Indicator species show pollution levels.

Key terms

Biodiversity: The variety of different species in a habitat.
Trophic level: Position of an organism in a food chain.
Quadrat: A square frame used to sample organisms in a habitat.
Transect: A line used to sample across a gradient.

Quick check

Explain one way farming can reduce biodiversity.
