Detailed explanation-1: -What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.

Detailed explanation-2: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Detailed explanation-3: -Chlorophyll. The green pigment in leaves is chlorophyll, which absorbs red and blue light from sunlight. Therefore, the light the leaves reflect is diminished in red and blue and appears green. The molecules of chlorophyll are large (C55H70MgN4O6).

Detailed explanation-4: -Biosynthesis. Chlorophylls in plant foods are synthesized from -aminolevulinic acid (ALA), whose role is demonstrated in the biosynthesis of the tetrapyrrole nucleus. Once ALA is formed, two molecules condense to form porphobilinogen (PBG) by converting an aliphatic compound into an aromatic one.
