The video explains photosynthesis, focusing on chlorophyll and other pigments like carotenoids and anthocyanins. It discusses how deciduous trees manage resources in winter by reducing photosynthesis, leading to chlorophyll breakdown and revealing other pigments. The process of leaf abscission, where trees shed leaves to conserve resources, is also covered.
