Photosynthesis
Quick fact
Plants produce enough oxygen for all the animals on Earth through photosynthesis.
Why this is interesting
Did you know that every bite of food you eat started as sunlight? Plants use a special process to turn light into energy.

Understanding Photosynthesis
Photosynthesis is like a solar-powered factory inside plants. Using sunlight, they take in carbon dioxide from the air and water from the soil to create glucose (food) and release oxygen as a byproduct. This process happens mainly in green parts of the plant, like leaves, where chlorophyll helps capture the light.
A deeper explanation
Photosynthesis works because plants use sunlight's energy to break down carbon dioxide and water into glucose, which they use for growth. Oxygen is released into the atmosphere as a waste product. This process not only fuels the plant but also provides oxygen for animals and plays a key role in regulating Earth’s climate.
