What is the Difference Between Mucilaginous Sheath and Gelatinous Sheath?

🆚 Go to Comparative Table 🆚

The mucilaginous sheath and gelatinous sheath are two different types of coverings found surrounding the cells of cyanobacteria. The key differences between them are:

  1. Composition: The mucilaginous sheath is composed of cellulose fibrils, while the gelatinous sheath is composed of collagens.
  2. Function: The mucilaginous sheath is also called the slime layer and is made of glycoprotein, which is used for several functions. The gelatinous sheath, on the other hand, is composed of gas vesicles, which are hollow protein structures that help regulate the locomotion of cells and retain colonies.
  3. Appearance: The mucilaginous sheath is glue-like in nature, while the gelatinous sheath is voluminous and fluffy.

Both sheaths protect cyanobacterial cells, help in binding cells together during the formation of cyanobacterial colonies, and aid in the locomotion of cells. They also provide protection against various environmental stresses.

    The main difference between the mucilaginous sheath and the gelatinous sheath lies in their composition. Here is a table summarizing their differences:

    Feature Mucilaginous Sheath Gelatinous Sheath
    Composition Composed of cellulose fibrils in a reticulate matrix Composed of collagens
    Function Also known as the slime layer, it is involved in cell separation and have adhesive properties Although it is also found surrounding the cells of cyanobacteria, its specific function is not mentioned in the search results

    Both sheaths are found in cyanobacteria, which are unicellular, photosynthetic prokaryotic organisms. They are also known as blue-green algae.
