Light from the sun hits the leaves of a plant.
Photosynthesis produces water and oxygen plus energy. It uses carbon dioxide and water to begin the process.
Photosynthesis begins in a plant's life cycle during the growth stage, specifically when the plant has developed leaves and is exposed to sunlight.

Leaves change colors for the following reasons: Once the water supply is cut off in the fall, no more chemical reactions take place for the leaves to make their own food. As the chlorophyll dissipate from the leaves and there is no water, the leaves begin to dry up. Once the manufactoring of food stops completely, the leaves dry up and fall from the tree. The water is turned on by nature in the spring and the leaves begin to make more food and give off oxygen.
The products of photosynthesis that begin cellular respiration are glucose and oxygen. Glucose is broken down in the process of cellular respiration to release energy, and oxygen is used as the final electron acceptor in the electron transport chain to produce ATP.
Leaves start to grow back in the spring due to increasing daylight hours and rising temperatures. This signals to the plant that it is time to begin producing new leaves for the upcoming growing season. The process is controlled by hormones within the plants that respond to environmental cues.
They could merge into one. In the process, they would emit strong gravitational waves.
Plants make their own food through photosynthesis. Plants need an optimum temperature (23-25 c), carbon dioxide and optimum light intensity (about 40%) to begin the process of photosynthesis.
