Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
A is a correct answer.

Answer:
The correct answer is Glomeromycota
Explanation:
Arbuscular mycorrhizae are characterized by the formation of unique structures, arbuscles, coils and vesicles of fungi of the phylum Glomeromycota. They are a type of endomicorrhiza in which the fungus penetrates the cortical cells of the roots of a vascular plant.
In this symbiotic association, the fungus helps the plant to capture nutrients such as phosphorus, sulfur, nitrogen and soil micronutrients. It is believed that the development of symbiosis with arbuscular mycorrhizae played a crucial role in the initial colonization of the earth by plants and in the evolution of vascular plants.
This symbiosis is a highly evolved mutualistic relationship found between fungi and plants.
