Sunlight is the ultimate source of energy for a plant. The sun provides plants with the ability to make their own food through a process of energy conversion known as photosynthesis.

Photosynthesis is the process by which plants take the sun's light energy and convert it into food. Without the sun, plants would be unable to produce foods, grow or thrive.
How It Works
The sun's light is absorbed by the leaves of the plant. The plant then changes the sun's energy into sugars, which feed the plant and fuel its ability to grow.
The photosynthesis process does not only benefit the plant, but benefits all organisms on earth. Through photosynthesis, plants release oxygen into the air, which humans and animals need to breathe. Also, healthy plants are major food sources for many other living things.
When planting a garden, it is important for gardeners to pay attention to the light requirements for the plants going into the soil. This ensures plants will get the correct amount of light for photosynthesis.
