Xanthophyll
Carotenoids are the pigments responsible for the yellow color of leaves in autumn. These pigments are present in the chloroplasts of plant cells and help in the process of photosynthesis. As the green chlorophyll pigment breaks down in the fall, the carotenoids are revealed, resulting in the yellow hues in leaves.
A lack of green pigment in plants is called chlorosis. Chlorosis occurs when there is a deficiency of chlorophyll, which is the pigment responsible for giving plants their green color and is essential for photosynthesis. This condition causes the leaves to turn yellow or pale.
