For the process of photosynthesis, a plant primarily needs the following three things:
-
Light Energy: Typically from sunlight, which provides the energy required to drive the chemical reactions involved in photosynthesis.
-
Carbon Dioxide (CO₂): This gas is absorbed from the atmosphere through the plant's leaves, specifically through small openings called stomata.
-
Water (H₂O): Water is absorbed from the soil through the plant's roots and transported to the leaves, where it is used in the photosynthesis process.
Together, these inputs allow plants to convert light energy into chemical energy, producing glucose and oxygen as a result.
