Can you explain the process of photosynthesis and its importance in greenhouse management?

Hiring managers ask this question to assess your understanding of a fundamental biological process and its practical application in greenhouse management. You need to explain that photosynthesis converts light energy into chemical energy, producing glucose for plant growth. Then, relate this to greenhouse management by discussing how optimizing light conditions can enhance photosynthesis and improve plant health and yield.

Example: Photosynthesis is a fascinating process where plants convert sunlight into energy, using carbon dioxide and water. This not only fuels their growth and development but also produces oxygen, which is vital for other life forms. In greenhouse management, we optimize light, temperature, and humidity to boost photosynthesis, ensuring robust plant health and yields. For example, strategically placing reflective surfaces can enhance light exposure and maximize growth.
