Mucigel is a slimy substance that covers the rootcap of the roots of plants. It is a highly hydrated polysaccharide, most likely a pectin, which is secreted from the outermost cells of the rootcap. Mucigel is formed in the Golgi bodies of such cells, and is secreted through the process of exocytosis. The layer of microorganism-rich soil surrounding the mucigel is called the rhizosphere. Primary and secondary roots in a cotton plant In vascular plants, the root is that organ of a plant body that typically lies below the surface of the soil (compare with stem). ...

Mucigel serves several functions, including:

• Protection of of rootcap; prevents desiccation
• Lubrication of rootcap; allows root to more efficiently penetrate the soil
• Creation of symbiotic environment for nitrogen fixing bacteria (i.e. diazotrophs) and fungi (which help with water absorption)
