Question

Two elements 12/6C and 16/8O form a compound 'z' which is required during the
photosynthesis by plants and is necessary for life.
​

Answer 1

Answer:  

Mg,Fe,Mn,Cu,Cl,P

Explanation:

Magnesium plays an important role in the process of photosynthesis because it forms the central atom of chlorophyll. Iron is required for the synthesis of chlorophyll and several electron transport proteins. Manganese is required in the photolysis of water during the process of photosynthesis. Copper participates in numerous physiological processes and is an essential cofactor for many metalloproteins. When excess copper is present in cells, it inhibits plant growth and impairs important cellular processes i.e., photosynthetic electron transport. Chlorine is an essential co-factor for photosynthesis. It also functions in the photolysis of water. Phosphorous helps in the process of photosynthesis by producing sugars and starch during the process and also helps in the conversion of these sugars into energy during the process of respiration. So the answer is Mg,Fe,Mn,Cu,Cl,P
