Question

The lubricant secreted by the root cap is called __.

Answer 1

The root is covered at the apex by a thimble-like structure called the root cap. It protects the tender apex of the root as it makes its way through the soil. The lubricant secreted by the cells in the root cap is called mucigel. It protects roots from desiccation and contains compounds that diffuse into the soil and inhibit growth in other roots. Mucigel is a complex polysaccharide containing sugars, organic acids, vitamins, enzymes, and amino acids.
