MYCORRHIZA
1) . term dissection, involves?
2) . t&c
3) . Hartig net and Vam **
4) . examples **
A
1). fungal roots (an example of plant and fungal mutualism, HENCE OBLIGATE RELATIONSHIP) plant may be an angiosperm or gymnosperm
2) . fungi: shelter, carbs (“nourishment from rot cortical cells”)
plants: surface area for absorption increases, essential nutrients (enhanced supply of water, N, P, S)
3). ECTOMYCORRHIZA: intercellular (between the outermost cellular layers of the host) hyphae forms a net: hartig net
ENDO: intercellular+intracellular (though most is within the root). VAM (vesicular arbuscular mycorrhizae) within root cortex
4).ECTO fungal partner: basidiomycetes (Boletus)
plant: Pinus (gymno)
ENDO zygomycetes, orchid root
