Lesson details
Key learning points
- Models are used in science to explain things that can be difficult to see or understand.
- The word summary and symbol equation for photosynthesis are simple models of the process.
- Photosynthesis can also be summarised using a model of the two main stages.
- In the first stage, energy from light is required to split water molecules into hydrogen and waste oxygen.
- In the second stage, the hydrogen is combined with carbon dioxide to make glucose.
Keywords
Model - a simpler representation of a complex thing or idea
Photosynthesis - the process used by producers to make their own food via a series of chemical reactions
Chloroplast - subcellular structure in which photosynthesis takes place
Prediction - a scientific prediction is a testable statement about a possible outcome, which could be tested in an experiment
Chlorophyll - green pigment in chloroplasts, to which energy is transferred by light
Common misconception
A common misconception is that photosynthesis is just one simple reaction, as depicted by the word equation and balanced symbol equation.
This explores the idea that the word equation and balanced symbol equation are useful but very simple models of photosynthesis, and also explores a slightly more detailed two-stage model of the process.
