Mycorrhizae are a symbiosis, or close, long-term relationship between two or more species. In this case, the species are the roots of a host plant and a mycorrhizal fungus. The word mycorrhizal means 'fungus root' in Greek. Approximately, 95% of vascular plants belong to genera that form mycorrhizal relationships, and it is likely that 80% of plant species associate with mycorrhizal fungi.
What is the function of pseudostratified ciliated columnar epithelium? Pseudostratified ciliated epithelium lines the nasal cavities, trachea, and bronchi. Its function is to protect these structures, secrete mucus by goblet cells, and move mucusâ¦ by cilia. 51 people found this useful.
Hence, it appears as though several layers of cells are present and the epithelium is called pseudostratified. The majority of cells composing the ciliated pseudostratified columnar epithelium are of three types: a) ciliated cells, b) goblet cells, and c) basal cells.ertain parts of the respiratory tract, such as the oropharynx, are also subject to the abrasive swallowing of food. To prevent the destruction of the respiratory epithelium in these areas, it changes to stratified squamous epithelium, which is better suited to the constant sloughing and abrasion.
