Answer:
They serve as phospholipid stores. They stop toxins from getting inside mitochondria.
Explanation:
lipid bilayers
The double membrane present in mitochondria and chloroplasts is thought to be a holdover from when prokaryotic bacteria were ingested by their eukaryotic hosts. The exterior membrane appears to have originated from the host cell itself, but the inner membrane, which now has several folds, appears to have originated from the bacterial membrane.
The development of the lipid bilayer depends on the dual character. While the hydrophobic component of the lipids is located inside the bilayer and prevents most molecules from passively diffusing across it, the hydrophilic regions of the molecule are in touch with the aqueous environment of the cell.
A bilayer's lipid components are always in motion, more so in more fluid bilayers and less so in more stiff ones. Additionally, cholesterol may increase rigidity and order.
A thin polar membrane comprised of two layers of lipid molecules is known as a lipid bilayer (or phospholipid bilayer). These membranes are flat sheets that surround every cell in a continuous barrier. The nuclear membrane enclosing the cell nucleus and the membranes of the membrane-bound organelles in the cell are all formed of a lipid bilayer, as are the cell membranes of practically all animals and many viruses. The lipid bilayer serves as a barrier, retaining ions, proteins, and other molecules where they are required while preventing their diffusion into unintended locations. Even though they are just a few nanometers wide[1], lipid bilayers are best suited for this function since they are impermeable to the majority of water-soluble (hydrophilic) compounds. Particularly impermeable are bilayers By transferring ions across their membranes utilising proteins referred to as ion pumps, cells are able to control salt concentrations and pH.
hence They serve as phospholipid stores. They stop toxins from getting inside mitochondria.
