Understand the process of photosynthesis: Photosynthesis is a chemical process used by plants, algae, and some bacteria to convert light energy into chemical energy stored in glucose. It primarily occurs in the chloroplasts of plant cells.
Identify the primary reactants: In photosynthesis, the primary reactants are carbon dioxide (CO₂) and water (H₂O). These substances are transformed into glucose and oxygen through a series of reactions.
Recognize the role of sunlight: Sunlight provides the energy required for photosynthesis. It is absorbed by chlorophyll, the green pigment in plants, which initiates the conversion of carbon dioxide and water into glucose.
Understand the chemical equation: The general chemical equation for photosynthesis can be represented as: . This equation shows the transformation of carbon dioxide and water into glucose and oxygen.
Clarify the incorrect options: Glucose and water, oxygen and glucose, and nitrogen and sunlight are not the primary reactants in photosynthesis. Glucose is a product, oxygen is a byproduct, and nitrogen is not directly involved in the photosynthetic process.
