. Facilitated diffusion is the type of molecular movement that occurs across a membrane in which certain molecules are carried by certain membrane proteins (carrier, gated channel, channel proteins) . The movement of molecules is therefore highly selective.
. The movement of molecules takes place down the concentration gradient i.e. from higher concentration to lower concentration.
. Thus, it does not require energy
. The movement of molecules takes place down the concentration gradient i.e. from higher concentration to lower concentration.
. Thus, it does not require energy

I. Mycorrhizal association between fungus and root of plant (Pinus) is often obligate.
II. Pinus and orchid seeds can germinate and grow into a plant in the absence of mycorrhizal association.
III. Absorption of water along with mineral solutes by root hairs is purely a process of diffusion.
IV. In apoplast pathway, movement of water takes place through cell wall and intercellular spaces.
V. Fungal hyphae provides sugar and organic material to the root.
