Answer:
Explanation:
Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.
Osmosis is transport in which the movement of a solvent occurs through a semipermeable membrane from a less concentrated solution into a more concentrated one without any protein.
Diffusion is a process where the molecule moves from one part to another part through the membrane.
Diffusion and osmosis are types of passive transport that do not require energy
This kind of movement does not involve transport proteins or other complex mechanisms.
Large polar molecules like glucose, amino acids, ions move through a membrane with the help of proteins
small non-polar molecules such as oxygen, carbon dioxide by diffusion and small polar molecules like water
large non-polar molecules like lipids can cross the membrane without the help of proteins by osmosis.
Thus, Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.
