¿Por qué las hojas son verdes? Parte 1

The video explores the role of chlorophyll in plants, explaining its ability to absorb sunlight and its contribution to the green color of plants. It discusses why chlorophyll doesn't absorb green light and speculates on historical reasons for plant coloration, including competition with purple archaea. The video concludes by suggesting that nature favors 'good enough' solutions rather than perfection, which is why plants are green instead of black.

What is the primary role of chlorophyll in plants?

• To absorb sunlight for energy

• To repel insects

• To produce oxygen

• To make plants appear red

Why do we see green when looking at leaves?

• Because leaves emit green light

• Because leaves reflect green light

• Because leaves are naturally green

• Because leaves absorb green light

What is one theory about why plants are green instead of another color?

• Green light is the most abundant

• Green light is the least absorbed by ancient purple organisms

• Green light is the most energetic

• Green light is the easiest to produce

What advantage did chlorophyll have over its purple competitors?

• It was easier to produce

• It could absorb all colors of light

• It had biochemical advantages

• It was more colorful

Why might plants not have evolved to have black leaves?

• Nature prefers 'good enough' solutions

• Black leaves are too hot

• Black leaves are too heavy

• Black leaves are too rare
