Question

In photosynthetic bacteria, the pigments occur in
(A) Chloroplasts
(B) Chromoplasts
(C) Chromatophores
(D) Leucoplasts

Answer 1

Hint: Photosynthetic bacteria are the prokaryotic microorganisms that have the ability to produce their own food with the help of the sunlight and the chlorophyll. This process is called photosynthesis and they are green in color due to the presence of chlorophyll.

Complete step by step answer:
Photosynthetic bacteria convert the water and the carbon dioxide into the oxygen and the sugar with the help of sunlight. These bacteria possess the chromatophores. The pigment containing cells is present in the chromatophores. Chromatophores are defined as the cells that possess pigment appear colored in the photosynthetic bacteria. This is called as the sunlight harvesting cells because they trap light for the process of photosynthesis in them.


Chlorophyll mainly absorbs the red light and the blue light from the sun and it reflects the light in the green region. These chlorophyll vary from each other by the changes in the double bond between the third or fourth carbon atoms. This chlorophyll is classified into two as primary and the accessory pigment. Chlorophyll a is considered as primary pigment and the chlorophyll b, c, d, carotenoids are the accessory pigments.

So, the correct answer is “Option C”.

Note:
An example for the photosynthetic bacteria are purple bacteria, green Sulphur bacteria. Mostly these photosynthetic bacteria are green, red, violet, brown and blue green colored due to the presence of photosynthetic pigment in them.
