Question

Which is the main light-absorbing pigment for photosynthesis?

Answer 1

Answer: The correct answer is- Chlorophyll a.

Chlorophyll is a green pigment that is found in the chloroplast of green plants and algae.

Chlorophyll a is considered as the primary pigment for photosynthesis as it is present in all photosynthetic eukaryotes.

In the first phase of photosynthesis (formation of food using carbon dioxide and water in the presence of sunlight), which is a light dependent phase, chlorophyll absorbs the solar energy and converts it into chemical energy in the form of ATP, and NADPH.

This energy is further utilized in the next phase (that is a light independent phase of photosynthesis) in formation of food (glucose) .

Answer 2

The main light-absorbing pigment for photosynthesis is chlorophyll.

Further Explanation:

Photosynthesis starts with the absorption of solar or light energy by the plant pigments called chlorophyll. This is primarily using in photosynthesis process and it present mostly in autotrophic organism. They are green pigment present in chloroplast of algae and green plant.

The first phase of photosynthesis the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide. The first phase occurs in the grana region of the chloroplast and involves the transport of electrons through photosystem II (PS II) followed by photosystem I (PS I). The energy gained by the chlorophyll molecule is transferred to PS II in the form of electrons. These electrons are passed on further through a series of electron transporter or carrier from PS II to PS I. In photosystem I, finally, the electron is gained by NADP+ to form NADPH.

The second phase of the photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.
