Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Ions typically cannot travel through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. The structure of the cell membrane does not easily allow ions to pass through, so they require specific channels or transport proteins to facilitate their movement into or out of the cell.
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
The cell membrane, which is a lipid bilayer, controls the movement of substances in and out of the cell through processes like diffusion, osmosis, and active transport. It acts as a selective barrier, allowing some substances to pass through while blocking others.
The permeability of the cell membrane controls which substances may pass in or out of the cell.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Lipid-soluble substances, such as oxygen, carbon dioxide, and small non-polar molecules, easily diffuse across the cell membrane. These substances can pass through the lipid bilayer of the membrane without the need for specific transport proteins.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
cell membrane
a substance such as sugar
Lipid-soluble substances can easily pass through the cell membrane due to the presence of phospholipids that make up the membrane. These substances can dissolve in the lipid bilayer and diffuse through it, allowing them to enter the cell more readily. In contrast, substances that are not lipid-soluble may require specific transport mechanisms to facilitate their entry into the cell.
Substances pass through the plasma membrane, although ot is not technically an organelle.

What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
