Physiological Functions In plant cells, pectin participates in growth, cell wall evolution and protection, cell adhesion, and wall pore formation. It helps maintain plant turgor and enhances the plant's ability to resist freezing and drought. In industry, pectin can be used in fields such as food and pharmaceuticals.
