A plant produces glucose during photosynthesis. State four different ways in which the glucose produced during photosynthesis can be used by the plant.
Written & reviewed by James Millett — Biology (Imperial College London), PGCE Science (University of Cambridge).
Model answer (4 marks)
1. Converted to starch for storage
2. Used in respiration to generate ATP
3. Converted to cellulose for cell‑wall construction
4. Converted to sucrose for phloem transport (or to nectar for pollination)

Examiner tips
- Use the exact wording from the mark scheme; list each use as a separate point
- Include the optional nectar option to show full knowledge
- Keep answers concise and avoid extra words
Common mistakes
- Writing 'glucose is used for energy' instead of specifying respiration
- Omitting the starch storage point
- Using non‑examiner terms like 'food' or 'energy source'
Mark scheme (4 marks)
- Glucose is converted to starch as an energy store
- Glucose is used in respiration to provide energy
- Glucose is converted to cellulose to build cell walls
- Glucose is converted to sucrose for transport in the phloem OR used to make nectar to attract insects for pollination
