Q

Photon

A

A particle representing a quantum of light or other magnetic radiation. It also carries energy proportional to the radiational system
(Photons that a specific pigment does not absorb are reflected by the pigment)

Q

Photosystem

A

a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms ( photosystems I and II ) involving different chlorophyll-protein complexes.

Q

A spectrum that the human eye can view

A

Visible light spectrum

17
Q

Major sites of photosynthesis

A

Chloroplasts

18
Q

What is photosynthesis

A

the process in which light energy is converted to chemical energy in the form of sugars.

19
Q

The photosynthesis equation

A

6CO2 + 6H2O → C6H12O6 + 6O2.

20
Q

What is a light-dependent reaction

A

a photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into (ATP) and (NADPH).
