No. It is produced by the liver and stored in the gall bladder. It is released when you eat a fatty meal.
do protists have cell membranes?
Every microbe has cell membranes but only plants have plasma membranes...
Yes all cells have cell membranes
The Cell Membrane
Which of these have very thin cell membranes?
I'm still working on this one myself. Bile functions as a biological detergent that emulsifies and solubilizes lipids, thereby playing an essential role in fat digestion. This detergent property of bile also confers potent antimicrobial activity, primarily through the dissolution of bacterial membranes. Bile salts are bile acids that have been conjugated to glycine or taurine. Bile breaks down fat into a more soluble form for digestion. Cell membranes of bacteria are made of phospholipid bilayers (lipids make up fats) which can be compromised by the bile (therefore the protection given by the cell membrane is lost and the cell can easily lyse, lose its contents). Also, as the bile salt breaks down to acid form, this could also be harmful to some bacteria. There may be more, but that's how I understand it, so far.

The Cell Membrane
It is used to produce hormones and cell membranes and is transported in the blood plasma of all mammals. It is an essential structural component of mammalian cell membranes. It is required to establish propermembrane permeability and fluidity. In addition cholesterol is an important component for the manufacture of bile acids, steroid hormones, and Vitamin D.

Membranes
Plants have cell membranes just inside their cell walls. The cell membranes control what passes into and out of the cell.
Cell membranes are not hard at all they are actually quite softish....
plant
Yes. Like plants they have both cell membranes and cell walls (but the cell walls have a different composition).
