Fluid moves into the cell through a passive process known as diffusion. Osmosis is the special name given to the diffusion of water across the semi-permeable membrane of the cell.
The cells go through the cell's membrane
Some molecules can't go through the cell membrane.
Glycogen has a had time passing through a cell membrane in comparison to water.

The cells go through the cell's membrane
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.

Because it is a small molecule, water can diffuse through the cell membrane.
The Mitochondria
Substances with a hydrophillic-lipophillic balance are permeable through the cell 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.

Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
The cell membrane controls the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to pass through while blocking others. This regulation helps maintain internal conditions necessary for the cell to function properly.
non penetrating substances may have molecules too large to go through a membrane or are chemically repelled by the membrane so it can't go through.
