Photosystems Flashcards
1
Q
What are the two parts of photosystems?
A
light harvesting systems
reaction centres
2
Q
What is the light harvesting systems?
A
contain accessory pigments e.g. chlorophyll b
plants can absorb a greater range in light wavelength
3
Q
What is the reaction centre?
A
contains primary pigments e.g. chlorophyll a
4
Q
What happens to photosystems during photosynthesis?
A
light energy is absorbed by the accessory pigment in the light harvesting system
more light energy is absorbed by primary pigments in the reaction centre - this energy is used to excite electrons
