Plant Pigments

The video tutorial explores plant pigments, starting with an introduction to their roles in plants. It covers chlorophyll, its types, and its crucial role in photosynthesis. The tutorial then discusses carotenoids, their colors, and their function as accessory pigments. Flavonoids, particularly anthocyanins, are explained in terms of their presence in plant vacuoles and their contribution to red coloration. Finally, phytochrome is introduced as a pigment that influences plant growth and development by absorbing light to trigger processes like seed germination and flowering.

What is the primary role of chlorophyll in plants?

• To protect against pests
