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.
The mucus and the ciliated pseudostratified columnar cells protect the body by filtering out or trapping substances in the upper respiratory tract that could cause damage if they enter the lungs. Pseudostratified tissue can also be found in other parts of the human body. The epididymis, where sperm mature in males, also makes use of this type of tissue. Other parts of the male reproductive system, such as the vas deferens, are lined with a type of pseudostratified columnar epithelium that is non-ciliated.
