Explanation:
Rearranged for the attached diagram:
a. Simple diffusion
b. Carrier-mediated facilitated diffusion
c. Channel-mediated facilitated diffusion
d. Osmosis
Facilitated diffusion is used to carry large molecules that are unable to cross at will the plasma membrane. However passive diffusion, along its concentration gradient, describes the passage of substances (small molecules and ions) across the membrane.
Through osmosis, water molecules travel across a semi-permeable membrane, from high-concentration regions to low-concentration regions, until a balance is achieved. This always happens inside the system along the concentration gradient.
Further Explanation:
Transmembrane proteins are transported from the extracellular fluid into the cytoplasm within the membrane, and are sometimes bound to glycoproteins (proteins attached). Transporting proteins across the plasma membrane allow ion movement and other complex, polar molecules that are normally prevented from passing through the membrane.
Carrier proteins and channel proteins are the two primary types of proteins found in membranes. Carrier proteins (also known as carriers, permeases, or transporters) bind the specific solution to be transported and undergo a series of conformation changes to transfer the substances across the membrane
