Question

In-plant metabolism, phosphorus play a major role in
(a)Evolving oxygen during photosynthesis
(b)Creating an aerobic condition
(c)Generating carbon dioxide during respiration
(d)Evolving carbon dioxide during respiration

Answer 1

Hint: Phosphorus is absorbed by the plants in the form of phosphates from the soil. The phosphorus thus absorbed helps in the formation of the cell membrane, certain proteins, nucleic acids, and is required in phosphorylation reactions.

Complete answer:
Plants require certain minerals called as essential elements for their proper growth and development. Phosphorus(P) is one of the seventeen essential elements required by the plants. This is because phosphorus is a chief constituent in the cell membranes, certain proteins, all the nucleic acids, and nucleotides, and is also essential for the phosphorylation reactions.
This phosphorus plays an indispensable role in cellular respiration and its absence will halt the process of respiration.
The process of cellular respiration is important for the oxidation of reduced substrates to Carbon dioxide (${C}{O}_{2}$) and water and phosphorus plays an important role in this process.

Additional Information: -The other essential elements for plants include carbon, hydrogen, oxygen, nitrogen, potassium, sulfur, calcium, magnesium, boron, chlorine, copper, iron, manganese, molybdenum, nickel, and zinc.
-Without these essential elements, a plant cannot complete its life cycle.
-These essential elements may be required in large amounts such as phosphorus or small amounts like half of these elements including iron, zinc, manganese, chlorine, etc.
The ones required in huge amounts are called macronutrients while those required in smaller amounts are called micronutrients.
So, the correct answer is, “Generating carbon dioxide during respiration”

Note: -Phosphorus is a very important macronutrient as it forms the nucleic acids and phospholipid membranes and thus is essential for both plants and animals.
-Phosphorus is a part of the ATP which provides energy to the organisms.
-A deficiency of phosphorus in plants may be noticed as a bluish-green discoloration.
