Plant Pigments

An introduction to plant pigments as organic compounds responsible for the diverse colors in leaves, flowers, and fruits, while also serving essential biological functions.

Explanation of chlorophyll as the primary pigment for photosynthesis. It functions by absorbing specific light wavelengths and using magnesium to facilitate energy conversion.

Discussion on carotenoids, which provide red, yellow, and orange hues and assist chlorophyll by capturing additional light energy during photosynthesis.

Details on flavonoids, specifically anthocyanins, which are stored in cell vacuoles and produce vibrant reds in flowers, fruits, and autumn leaves.

Overview of phytochrome, a pigment that acts as a sensory switch to trigger growth processes like seed germination, leaf development, and flowering.
