Fotosíntesis (método de medición de presión de oxígeno) (con Cobra4)

Num.Producto: P4110260

Principle

Photosynthesis leads to the production of oxygen, which in turn causes the pressure to rise. In this experiment the photosynthesis rate of a plant is determined by measuring the oxygen pressure increase, in white and green light as well as in the dark.

Benefits

  • Compact, easily transportable setup
  • For both demonstration and student experiments
  • Flexible experimenting thanks to wireless data transmission
  • Additional experiment in plant physiology and biochemistry can be performed with few modifications
  • Data acquisition with tablets possible
  • With detailed experiment guide

Tasks

  1. To compare the increase in oxygen pressure during photosynthesis in white light, green light and in the dark.
  2. To discuss the reasons for the differences of the pressure curve rise.

What you can learn about

  • Photosynthesis
  • Intensity and colour of the light
  • Pressure measurement
