Ectomycorrhizae and Endomycorrhizae
Captions available
The idea
Mycorrhizae, per Bio 2053, divide by where the fungus sits: ectomycorrhizae sheathe the root outside its cells, while endomycorrhizae penetrate the root cell walls.
In practice
Ectomycorrhizae's fungal mantle around a conifer's roots reaches soil pores the bare root surface never could alone.
Where people slip
Endomycorrhizae, found in most terrestrial plants, are far more common than ectomycorrhizae, typical of specific forest trees.
