Gynostemma pentaphyllum, a plant, grows better in shade than in full sunlight. The plant's photosynthesis rate is higher under shade, reaching its peak at 11:00. In full sunlight, the photosynthesis rate drops at midday. The plant's photosynthesis is influenced by light intensity, humidity, and stomatal conductance. High light intensity can decrease photosynthesis, while humidity and stomatal conductance affect transpiration. This plant prefers shady conditions for optimal growth, so light levels should be considered when cultivating it.
