Refer to the figure, which shows a fungal interaction with a plant cell. Which statement is an accurate description of this interaction?
A) The fungal hyphae have penetrated the plant cell and have broken through the cell membrane in order to obtain nutrients from the plant.
B) The fungus has formed haustoria that push directly against the plant plasma membrane in order to absorb nutrients secreted from the plant cell.
C) The fungal hyphae are ectomycorrhizae and have entered the plant cell in order to provide nitrogen in exchange for carbon compounds.
D) The fungus and plant cell have joined together in a symbiotic association to form a lichen.
E) The fungal hyphae are part of an arbuscular mycorrhizal network in which the fungus provides carbon to the plant in exchange for nitrogen.

The figure shows a fungal interaction with a plant cell where haustoria (specialized hyphae) are formed by the fungus that push directly against the plant plasma membrane in order to absorb nutrients secreted from the plant cell. This type of interaction is known as biotrophic.
