IBDP Biology C1.3 Photosynthesis

Flashcards covering key concepts related to photosynthesis and chromatography as outlined in the IBDP Biology C1.3 lecture notes.

Photosynthesis

The process by which green plants and some organisms use sunlight to synthesize foods with the help of chlorophyll.

Light energy transformation

The change of light energy into chemical energy during photosynthesis.

Word equation for photosynthesis

carbon dioxide + water → glucose + oxygen.

By-product of photosynthesis

Oxygen produced during photosynthesis, resulting from the splitting of water.

Chromatography

A laboratory technique for the separation of a mixture by passing it through a stationary phase and a mobile phase.

Rf value

The ratio of the distance moved by the pigment to the distance moved by the solvent front in chromatography.

Absorption spectra

A graph showing the wavelengths of light absorbed by a pigment.

Action spectrum

A graph that represents the rate of photosynthesis at different wavelengths of light.

Limiting factors of photosynthesis

Conditions that can limit the rate of photosynthesis, such as light intensity, carbon dioxide concentration, and temperature.

Impact of increased CO2 on photosynthesis

Increased carbon dioxide can enhance the rate of photosynthesis, but this effect varies among plant species.
