Phospholipids
The cell membrane or cell wall.
Phospholipids
The lipid bilayer prevents the cell from dissolving in water.

Nonpolar Fatty acid chains
The part of the cell membrane that prevents organisms from dissolving in water is the phospholipid bilayer. This structure has hydrophobic (water-repelling) fatty acid tails that face inward, away from water, while the hydrophilic (water-attracting) phosphate heads face outward. This arrangement creates a barrier that regulates what enters and exits the cell, helping to maintain the integrity of the cell in aqueous environments.
The part of the cell membrane that is nonpolar and prevents the cell from dissolving is the phospholipid bilayer. This bilayer consists of hydrophobic (water-repelling) fatty acid tails that face inward, away from water, while the hydrophilic (water-attracting) phosphate heads face outward towards the aqueous environment. This arrangement creates a semi-permeable barrier that maintains the integrity of the cell by preventing the free passage of water-soluble substances.

The Cell membrane, along with its integrated proteins. In prokaryotes the Cell membrane is bolstered by the [mostly cellulosic] Cell Wall; in eukaryotes the Cell membrane is bolstered by the [glyco-protein] Cell Coat.
Fatty acid chains
The epiglottis is the part of the body that prevents food from entering the lungs. It is a flap of cartilage located at the base of the tongue that covers the trachea during swallowing, directing food and liquids into the esophagus instead. This mechanism helps to ensure that the airway remains clear and prevents aspiration, which could lead to respiratory complications.
