What are ectomycorrhizae?
Quick Answer
Ectomycorrhizae are fungi that form a sheath around plant roots without entering the root cells. They are especially common on many trees.
The Full Story
Ectomycorrhizal fungi wrap around the outside of young roots and form a dense network called the Hartig net between root cells. They do not usually penetrate the plant cells themselves. This type of symbiosis is especially important for many temperate and boreal trees, including pines, oaks, and birches. The fungi help the tree obtain water and nutrients, while the tree supplies carbohydrates made by photosynthesis.
