Plants make their own food through a process called photosynthesis.
Photosynthesis requires sunlight, water, and carbon dioxide.
Plants absorb water through their roots.
Leaves take in carbon dioxide from the air.
Chlorophyll gives plants their green color and helps capture sunlight.
Photosynthesis produces glucose, which is the plant's food.
Oxygen is released into the air during photosynthesis.
Plants are called autotrophs because they make their own food.
Algae and some microorganisms also perform photosynthesis.
Photosynthesis helps provide oxygen for most living things on Earth.
