How a Japanese maple tree having only red leaves can carry on photosynthesis?

A Japanese maple tree with only red leaves can still carry out photosynthesis because the red pigments, primarily anthocyanins, can absorb light in the blue and green wavelengths, which are essential for photosynthesis. While chlorophyll is typically responsible for capturing light energy, the presence of anthocyanins allows the tree to utilize different light wavelengths effectively. Additionally, the underlying chlorophyll in the leaf tissue can still function, enabling the tree to produce energy even if the leaves appear predominantly red. Thus, the tree can adapt to its environment and continue to photosynthesize.
