Explain two ways materials can enter the cell through passive transport. Include in your the types of substance that is transported, the concentration gradient, and any structures in the cell membrane required to be used.

Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:
