How Do You Make an Apple From a Rock?

Plants make organic material (like stems, leaves, and fruit) from inorganic nutrients (as found in rocks, soil, or water)

A chemical called chlorophyll gives plants their green color.

Plants make food inside their bodies by the process called photosynthesis.

All animal life on Earth (including humans) depends on the oxygen produced by photosynthesis!

Plants absorb carbon dioxide from the air. Too much carbon dioxide will cause the Earth to heat up (the greenhouse effect).
