Cambios en la condición lumínica en bosques caducifolios

Principle

Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the ...

Efecto de la temperatura del suelo en la germinación y cre- cimiento de plantas

Principle

Genetically determined growth processes in plants are primarily triggered or inhibited by special phytohormones. However, external factors such as light, temperature, water, oxygen and air humidity play a decisive role in these processes. With
regard to temperature, there are ...

Transpiración de las hojas (con Cobra4)

Principle

Plants "sweat" just as people do and are thereby physiologically and morphologically suited to their specific environment. They transpire at high temperatures and pass water to the environment. Transpiration also serves for the transport of water and nutrients. The underpressure ...

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 ...

Permeabilidad iónica de la membrana celular (con Cobra4)

Principle

The cell membrane controls the transport of nutrients and water into the cell, and of waste products and water out of the cell. This can take place passively, e.g. on the basis of osmotic processes (differences in concentration), as well as actively.

Benefits

  • Compact, easily ...

Inhibición de las encimas por el sustrato (con Cobra4)

Principle

The enzymatic hydrolysis of urea in aqueous solution liberates carbon dioxide and ammonia. The ions of these compounds increase the conductivity of the solution. Inhibition of the enzyme by the substrate occures at excessive substrate concentrations.

Benefits

  • Compact, ...

Inhibición de enzimas (envenenamiento de enzimas) (con Co- bra4)

Principle

The enzymatic hydrolysis of urea in aqueous solutions liberates carbon dioxide and ammonia. The ions of these compounds increase the conductivity of the solution.

Benefits

  • Compact, easily transportable setup
  • For both demonstration and student experiments
  • Flexible ...

Actividad enzimática de la catalasa (con Cobra4)

Principle

Catalase is an enzyme that - in humans - is found predominantly in the liver and erythrocytes. It decomposes hydrogen peroxide, which is a toxic byproduct of cellular respiration, into water and oxygen.

Benefits

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