Gas Balance

Carbon dioxide release of plants through respiration

Particle motion (diffusion, thermal agitation)

Photosynthesis (O2 pressure measurement) (with Cobra4)

Principle

Representation of the photosynthesis rate of a plant by measuring the oxygen pressure increase, in
white and green light as well as in the dark.

Photosynthesis (bubble-counting-method)

Principle

Measurement of the photosynthesis rate as a function of light intensity by counting the oxygen bubbles
that are released by a water plant.

Glycolysis (pressure measurement, with Cobra3 Basic-Unit)

Principle

Glycolysis (measurement of pressure)

Tasks

1. To identify glycolysis by measuring the production of Co2 and plotting graphs.
2. To investigate the influence of temperature and pH on metabolic activity.
