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. The inverse is true when measuring carbon dioxide concentration.

Tasks

Determine the oxygen formation and carbon dioxide consumption during photosynthesis.
Determine the oxygen consumption and carbon dioxide formation during cellular respiration.

Learning objectives

The aim of this experiment is to investigate the metabolism of plants with regard to the oxygen and carbon dioxide concentration in a hermetically sealed container.

Benefits

Clear and easy to follow experiment guide with reference to everyday life including protocol questions
Compact, easy to transport experimental set-up
Suitable for demo experiments and lab courses
Flexible experiment procedure thanks to wireless data transmission
