Sagot :
Methane CH4 molecule can diffuse across the plasma membrane . So the correct answer is CH4.
Passive diffusion is a nonselective mechanism that allows any molecule that can dissolve in the phospholipid bilayer to traverse the plasma membrane and establish equilibrium between the inside and outside of the cell. It's crucial to note that only tiny, mostly hydrophobic compounds can diffuse significantly through a phospholipid bilayer.
Gases (like O2 and CO2), hydrophobic substances (like benzene), and tiny polar but uncharged substances (like H2O and ethanol) can all diffuse across the plasma membrane as a result. However, some biological molecules cannot dissolve in the phospholipid bilayer's hydrophobic interior.
