Principle

This experiment shows that oxygen is produced during photosynthesis when the plant is exposed to light, while oxygen is consumed in the dark by the cellular respiration of the plant.

Benefits

• Especially understandable and didactically prepared description of the experiment (reference to everyday life etc.) including protocol questions
• Compact, easily transportable experimental set-up
• Suitable for demo experiments and lab courses
• Flexible test execution thanks to wireless data transmission

Tasks

1. Determination of oxygen formation during photosynthesis
2. Determination of oxygen consumption during cellular respiration

Learning objectives
