|Why do leaves change color?|
It is these chlorophylls which give leaves their green color. Chlorophylls are constantly used up during photosynthesis and are constantly replaced by the tree during its growth period.
However, as the growing season ends, the transfer into the leaf of chlorophylls and other important chemicals such as phosphates begins to taper off as a thin layer of cork develops at the stem of each leaf where it attaches to the branch.
