Sunlight gives plants energy - actual tiny packets of energy to jump-start reactions between very small particles inside the plant. These reactions help plants make other small particles they need to breathe (in the case of plants needing carbon dioxide or other gases), to eat (absorb and break down nutrients to make other things), and to expel waste (funnel products of their "eating" and "breathing" out of themselves).

Many of the small particles made with the help of sunlightmake up parts of the plant stalk and leaves, and by accumulating more cells in its stalk and leaves, a plant grows taller, larger, and more mature.

Plants use the light from the sun as energy. Plants use the light to turn water and carbon dioxide into sugars and oxygen. The oxygen becomes the oxygen we breathe, and the sugars become food for the plant.

Sunlight is a plant's food, which gives it energy and helps it grow! The sun is used by the plant in a process called photosynthesis, where the plant converts the sun's light into energy. Humans and animals then eat the plants, which gives them energy!
