Chlorophyll
Phosphorus
Polymer
Answer is Wrong!
Answer is Right!
The correct answer is B. Chlorophyll.
Chlorophyll is a green pigment found in plants and algae. It is necessary for photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
Chloroform is a colorless, flammable liquid that is used as a solvent and anesthetic. It is not necessary for photosynthesis.
Phosphorus is a non-metallic element that is found in many minerals. It is necessary for the growth of plants, but it is not directly involved in photosynthesis.
Polymer is a large molecule made up of many smaller molecules. It is not necessary for photosynthesis.
