In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluids because they cannot be stacked closlely together. Of what advantage would this be for herbaceous plants that live through the winter? (Hint: what happens to bacon grease or the grease on top of soup when you put it in the refrigerator?)
