10- How are photosynthetic bacteria and chloroplasts related

Solution

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.
