Final answer:
The reactants leading to the production of auxin in plants are water and carbon dioxide. These reactants are used in the process of photosynthesis, where plants convert water and carbon dioxide into glucose and oxygen.
Step-by-step explanation:
In the chemical reactions leading to the production of auxin in plants, the reactants are water and carbon dioxide. These reactants are used in the process of photosynthesis, where plants use sunlight and chlorophyll to convert water and carbon dioxide into glucose and oxygen. The glucose produced during photosynthesis is then utilized by the plant to produce auxin, which helps in various growth and development processes.
