Photosynthesis and Plant Responses: Light and Photosynthesis

The video explains the composition of a rainbow, which consists of colors like red, orange, yellow, green, blue, indigo, and violet, originating from sunlight or white light.

As seasons change, chlorophyll diminishes, revealing other pigments like carotenoids, which give leaves their autumn colors.
