In a greenhouse, where is the best position to place a plant for optimal sunlight exposure?

Placing a plant within its optimal range is crucial for maximizing its exposure to sunlight, which directly supports its photosynthetic processes. The optimal range refers to the specific conditions—such as light intensity, temperature, and moisture—under which the plant can grow best, ensuring that it receives enough sunlight to perform photosynthesis effectively without undergoing stress.

When plants are in their optimal range, they can utilize sunlight efficiently to convert carbon dioxide and water into glucose and oxygen, promoting healthy growth and development. This position allows plants not only to thrive but also to enhance their resilience against environmental changes, pests, and diseases.

Other options imply less favorable conditions. Being within the limits of tolerance may mean the plant could survive, but it might not perform optimally. The photosynthetic limit indicates that the plant can only photosynthesize up to a certain point, potentially leading to diminishing returns on energy gained. Being at zones of stress would further hinder growth and well-being, as conditions would likely induce adverse effects on the plant.
