Fotosíntesis

Fotosíntesis (método de conteo de burbujas) (con Cobra4)

Principle

To measure the dependence of photosynthesis on light.

Tasks

1. To measure the dependence of photosynthesis on light by counting the oxygen bubbles given off by an aquatic plant
2. To investigate the influence of the carbon dioxide content of the water on the rate of ...

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

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, ...

Importancia del dióxido de carbono para la fotosíntesis y la respiración celular

Principle

This experiment shows that carbon dioxide is consumed during photosynthesis when a plant is exposed to light, whereas carbon dioxide is produced through plant cellular respiration when dark.

Benefits

• Compact, easily transportable setup
• For both demonstration and ...
