Explanation / Answer
Answer:
1: The chlorophyll consists of two parts. Those are a ring called 'porphyrin ring' which shows magnesium in the centre and a long hydrocarbon tail called 'phytol' .
2: chlorophyll a appears in Green
3: Chlorophyll a absorb light of 430nm and 662nm
4: Chlorophyll a reflects green light, thus appears green.
5: The chlorophyll b appears in Green
6: Chlorophyll b absorb light of 453nm and 642nm
7: The carotenoids appear in orange and yellow color.
8: The carotenoids are accessory pigments. They absorb light and transfer the light energy to chlorophyll pigments.
