Temperature Control Module

Photosynthesis is a series of chemical reactions. Heat speeds up chemical reactions by adding kinetic energy to the reactants or enzymes. Therefore, heat speeds up photosynthesis, unless another factor, such as weak light, limits photosynthesis. However, too high a temperature can destroy or denature the enzymes, hindering their proper function and decreasing the photosynthetic rate. Due to this, the rate of photosynthesis in relation to temperature forms a curve.

Low temperatures, such as being cold enough for water to freeze, can be very harmful to a plant. At higher temperatures, the stomata close to prevent water loss. This also stops gas exchange, resulting in decreased photosynthesis. The CI-510CS allows the user to adjust the temperature of the leaf in the chamber and investigate the effects ranging from -25 to +25°C from ambient temperature.
