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.

This is a low power view of the trachea. The luminal surface of this organ is covered with a ciliated, pseudostratified columnar epithelium. This medium power view of the tracheal epithelium reveals its pseudostratified columnar architecture. Nuclei are seen at different levels within the epithelium giving the appearance of a stratified epithelium.
