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.
Simple columnar epithelium consists of a single layer of tall (columnar cells). Simple columnar epithelium is usually involved in active secretion and/or absorption of material across the single cell layer, or (if ciliated) in movement along the surface. By convention, a stratified epithelium is described according to the shape of cells on its free surface. 2  Regardless of whether the surface cells are squamous, cuboidal, or columnar, the underlying cells are usually cuboidal.
