Textbook Question
Chapter 4, Problem 13PS
Plant seeds store oils as droplets. An oil droplet membrane is a single layer of phospholipids. Draw a model for such a membrane. Explain why it is more stable than a bilayer.

Students have asked these similar questions
If you place phospholipids in an oil-based solution, would they still self-assemble into a bilayer? If so, describe its structure.
Draw the basic structure of a lipid bilayer and label thehydrophilic and hydrophobic regions. Why is the cytoplasmicmembrane a good permeability barrier?
Explain the following statement: The structure of all biomembranes depends on the chemical properties of phospholipids, whereas the function of each specific biomembrane depends on the specific proteins associated with that membrane.
