No, there are specific cell membranes that allow only certain molecules to pass through. Some stay open and others must be opened ( like a gate ).

∙ 11y agoNo, not all molecules can diffuse through all cell membranes. The ability of a molecule to diffuse through a cell membrane depends on its size, charge, and solubility in lipids. Small, non-polar molecules can generally pass through the lipid bilayer of cell membranes via simple diffusion, while larger, polar molecules may require specific transport mechanisms.

∙ 11y agoNo. In order to diffuse through a membrane the molecule must be hydrophilic.

Molecules that are charged or polar, such as ions, glucose, and amino acids, diffuse through cell membranes by facilitated diffusion. This process relies on carrier proteins or channel proteins to help facilitate the movement of these molecules across the membrane.
Small, non-polar molecules like oxygen, carbon dioxide, and water can passively diffuse through cell membranes and be absorbed into the blood. Lipid-soluble molecules and small uncharged molecules can also passively cross cell membranes to enter the bloodstream.
Sugar molecules do not diffuse through a plant cell membrane because they are too large and polar to pass through the hydrophobic interior of the lipid bilayer. Instead, sugar molecules are transported across the membrane by specific transport proteins, such as sugar transporters, that facilitate their movement into the cell.
Cell membranes are selectively permeable as they allow certain molecules to pass through while restricting others. For example, cell membranes allow small molecules like water and gases to pass through freely, while larger molecules like proteins and ions require specific channels or transporters to move in and out of the cell.
Small molecules such as oxygen, carbon dioxide, and water can pass through cell membranes by diffusion. Lipid-soluble molecules like alcohol and steroid hormones can also diffuse through cell membranes.

Starch molecules are too large to pass through the pores of a partially permeable membrane. The size exclusion limit of the membrane restricts the passage of larger molecules like starch while allowing smaller molecules like water to pass through via osmosis.
Sugar passing through an animal cell is called facilitated diffusion. This process involves the use of transport proteins to help the sugar move across the cell membrane.

No, smaller molecules generally diffuse more readily than larger molecules because they can move through pores and gaps in substances more easily due to their smaller size. This is why smaller molecules like oxygen and carbon dioxide can diffuse through cell membranes more quickly than larger molecules like proteins.
glucose molecules will diffuse out of the cell. apex
Through facilitated diffusion
Every cell in the body has access to essential nutrients through the circulatory system. Molecules in the blood diffuse out of capillaries where their concentration is high, into surrounding tissue fluid where they are required. For small molecules, such as water and gasses, this is allowed by tiny holes in the membranes just big enough for them to pass through. Larger molecules such as glycogen and proteins must be drawn into cells by a process called active transport, where gates embedded in the cell membranes are use ATP to pull desired molecules into the cell.
Oxygen is a small molecule that can easily diffuse across cell membranes, including the membranes of red blood cells. This passive diffusion process is faster and more efficient than active transport for molecules like oxygen that are able to freely move across cell membranes.
