Question

In photosynthesis solar energy is captured by the pigment called______.

Answer 1

Hint:Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.

Complete answer:
Photosynthesis is the process by which plants from bacteria use the energy from sunlight to produce glucose from carbon dioxide and water. Glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.
The conversion of usable sunlight energy into chemical energy is associated with the action of the green pigment chlorophyll.

Chlorophyll is a complex molecule. Several modifications of chlorophyll occur among plants and other photosynthetic organisms. All photosynthetic organisms have chlorophyll a. accessory pigments types of energy that chlorophyll does not absorb.

Accessory pigments include chlorophyll b (also c, d and e in Algae and protestants) xanthophyll and carotenoids. Chlorophyll absorbs its energy from the violet-blue and reddish orange- red wavelength and little from intermediate (green-yellow-orange) wavelength.

All chlorophylls have:
1. A lipid soluble hydrocarbon tail.
2. A flat hydrophilic head with a magnesium iron at its center, different Chlorophylls have different side groups on the head.

The tail and head are linked by ester Bond.
Chlorophyll, natural green pigments, takes part widely in the nutrition of humans. A high level of chlorophyll in especially green vegetables increases its importance in terms of biological function.

Therefore, in photosynthesis solar energy is captured by the [pigment called chlorophyll.


Note: There are four types of chlorophyll,
i) Chlorophyll a: It is found in higher plants, algae and cyanobacteria.
ii) Chlorophyll b: It is found in higher plants and green algae.
iii) Chlorophyll c: It is found in brown algae, diatoms and dinoflagellates.
iv) Chlorophyll d: It is found only in red algae.
