Question

Quizplus · Accepted Answer

Plants that can survive winters in Northern Ontario would have a higher percentage of unsaturated fatty acids in their plasma membranes. This is because unsaturated fatty acids have kinks in their hydrocarbon tails, which prevent the molecules from packing tightly together and solidifying at low temperatures. In contrast, plasma membranes of plants growing in warmer regions would have a higher percentage of saturated fatty acids, which have straight hydrocarbon tails that pack together tightly to maintain membrane fluidity at high temperatures.
