Understanding Why Leaves Change Color in Fall

The video explores why leaves change color in the fall. Initially, it discusses common misconceptions, such as trees dying, and then delves into the scientific explanation. Leaves contain chlorophyll, which makes them green. In fall, trees reabsorb nutrients from chlorophyll to store for winter, causing leaves to lose their green color. Other pigments in leaves, like yellow and red, become visible. The video concludes with a summary and invites viewers to vote on the next topic.
