Answer:
The part of plants that contains structures needed to absorb sunlight and carbon dioxide is the chlorophyll.
Explanation:
Photosynthesis is the process by which plants produce glucose.
The process of photosynthesis requires light energy which plants get from trapping the sunlight. The area of the plant which contains structures to absorb sunlight and for photosynthesis is the chlorophyll. Chlorophyll contains a green coloured substance termed chloroplast. Chloroplast is the site where photosynthesis takes place. Chloroplast is also the structure which is responsible for giving green colour to the leaves.

Answer:
The question is incomplete. 
However, I notice that your question is mainly dealing with 
"Nucleotides with a single ring structure"
I tackled that part, also providing explanation to the point you focused on.
Explanation:
Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.
Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.

The number of amino acids that will be in the polypeptide chain produced by the normal DNA or MRNA sequence is usually 30 amino acids. Although the number of amino acids depends on the function of the generated DNA or RNA. The types of amino acids also differ depending on the function.
