How are traits passed down through generations?

D. Point into Leaf: water(H₂O), carbon dioxide (CO₂) sunlight, Point away from leaf: Sugars, oxygen (O₂)

Explanation:

Photosynthesis is the process used in the production of chemical energy in the form of energy containing organic compounds and oxygen from atmospheric carbon dioxide and liquid water enabled with the energy captured from light (mainly Sunlight) by the chlorophyll in green plants and other organisms

The basic chemical reaction involved in a photosynthesis reaction is presented as follows;

                                   Sunlight

                                         ↓

      CO₂           +  H₂O (l)  →   C₆H₁₂O₆   +    O₂

Carbon dioxide  Water        Glucose       Oxygen
