Question:
The central, structural atom in the primary photosynthetic pigment is
The central, structural atom in the primary photosynthetic pigment is
Updated On: Aug 15, 2022
- $Fe$
- $Mg$
- $Cu$
- $Zn$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Chlorophyll is the primary photosynthetic pigment because it performs primary reaction of photosynthesis which involves conversion of light into chemical energy. A chlorophyll molecule consists of a head called porphyrin and.a tail made up of long chain alcohol called phytol. Magnesium $(Mg)$ forms the central atom of the porphyrin ring of chlorophyll molecule.

I. Joseph Priestley (1770): Showed that plants have the ability to take CO2 from the atmosphere and release O2.
II. Jan Ingenhousz (1779): Release of CO2 by plants was possible only at night and only by the non-green parts of plants.
III. Julius Von Sachs (1884): Green parts in plants produce glucose which is stored as starch.
IV. C. Van Niel (1931): Photosynthesis is essentially a light dependent reaction in which hydrogen from an oxidizable compound reduces CO2 to form carbohydrates.

Photosynthesis in Higher Plants
Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
