1. Photosynthesis and plant nutrition

Key Concepts & Definitions

  • Photosynthesis : Photosynthesis is the process where plants make their own glucose using light energy.
  • Chloroplasts : Chloroplasts are the cell structures where photosynthesis takes place.
  • Chlorophyll : Chlorophyll is the pigment that absorbs light energy for photosynthesis.
  • Glucose : Glucose is the carbohydrate produced by photosynthesis that can be used or stored by plants.

Essential Points

  • Photosynthesis word equation is Carbon dioxide + Water → Glucose + Oxygen.
  • Chlorophyll absorbs light energy, so plants need it to photosynthesise.
  • Glucose can be used for respiration, stored as starch, or used to make cellulose.
  • Factors affecting photosynthesis include light intensity, carbon dioxide concentration and temperature.

Memory Hook

Chlorophyll turns light into glucose (food), giving oxygen away.
