Why Are Leaves Green? Part 2

The video explores the role of chlorophyll in photosynthesis, highlighting its unique green color and efficiency in absorbing light. Despite its poor absorption of green light, chlorophyll's layered arrangement in leaves allows for effective energy capture and distribution. The video compares chlorophyll's sugar-making capabilities with those of purple bacteria, emphasizing the superiority of green photosynthesis, which accounts for the vast majority of Earth's natural productivity. The discussion raises questions about the potential for different photosynthetic processes on other planets.

What are the two main functions of light-absorbing molecules in plants?

Discuss the significance of chlorophyll in the context of Earth's natural productivity.
