Dear student,
A polymer is a large molecule (macromolecule) composed of repeating structural units typically connected by covalent chemical bonds. Lignin is an example of a complex polymer that forms an extensive network within the cell walls of certain plants and confers strength and rigidity to the cell wall. It is one of the chief substances found in wood.
Coloured leaves have chlorophyll too. It is just that they are masked by other colour pigments.  Plants with leaf color other than green perform photosynthesis just like green leaves. If they did not, they would not live. The chlorophyll needed for photosynthesis is masked among the colorful pigmentation.
