economic products - cell walls are important for products such as paper, wood, fiber, energy, shelter, and even roughage in our diet. ... These arabinogalactan proteins, or AGP's, seem to be tissue specific and may function in cell signaling. They may be important in embryogenesis and growth and guidance of the pollen tube.
