Which of the following is not a function of the eukaryotic glycocalyx?

The glycocalyx in eukaryotic cells is a gelatinous coating that surrounds the cell membrane and serves several essential functions. It primarily provides protection to the cell, helping to shield it from physical damage and immune system attacks. Additionally, the glycocalyx plays a role in cell recognition, allowing cells to communicate and identify each other through specific receptor interactions. Furthermore, it aids in attachment to surfaces, which can be critical for cells forming tissues or establishing colonies.

Movement, however, is not a function associated with the glycocalyx. Eukaryotic cells typically achieve movement through structures such as flagella and cilia, which are made up of microtubules and are distinct from the glycocalyx. Therefore, while the glycocalyx contributes to various vital processes, it does not facilitate movement, making this the correct conclusion.
