Study Notes
Photosynthetic Pigments
- Photosynthetic pigments are classified into two classes: primary pigments and accessory pigments.
- Chlorophyll a is the primary pigment, responsible for trapping solar energy and converting it into electrical and chemical energy.
- Chlorophyll a is known as the reaction centre.
Accessory Pigments
- Accessory pigments include chlorophyll b and carotenoids.
- These pigments absorb energy and pass it on to chlorophyll a (Chl.a) molecules.
- Accessory pigments are also known as harvesting centre.
Photo Systems
- Primary pigments (reaction centre) and accessory pigments (harvesting centre) together form photo systems.
