Answer:
Chlorophyll a is absent in Bacteria which is also a photosynthetic bacteria.
Explanation:
The chlorophyll a is a pigment that absorbs blue, red, and violet light and reflects green light majorly. This is the major pigment that is responsible for the maximum absorption of sunlight and this is the reason why most of the plant leaves are green in color.
Some of the ‘bacteria’ do not have this pigment whereas they prepare food by the chemosynthetic pathway.
