What is the role of chlorophyll in photosynthesis?
Chlorophyll is the key pigment in photosynthesis that captures sunlight. It converts this light energy into chemical energy by exciting electrons, which are then transferred through a series of reactions. This process produces ATP and NADPH, essential for powering the Calvin cycle to convert carbon dioxide into glucose, vital for plant growth and energy.
Chlorophyll:
- A pigment molecule found within chloroplasts
- Gives plants their green color
Is PPF the same as PAR?
PAR stands for Photosynthetic Active Radiation which is defined as photons emitted between the wavelength of 400 and 700 nanometres.
PPF stands for Photosynthetic Photon Flux and measures the amount of photons within the PAR Area. PPF is the toatal amount of light emmited by the light source (µmol/s)
