The membranes of winter wheat are able to remain fluid when it is extremely cold by .A) increasing the proportion of unsaturated phospholipids in the membraneB) decreasing the percentage of cholesterol molecules in the membraneC) decreasing the number of hydrophobic proteins in the membrane

Answer is A. Increasing the proportion of unsaturated phospholipids in the membrane.

Explanation:

A lot of plants can adapt to temperature changes by altering the ratio of unsaturated to saturated fatty acids within their cell membranes. In the winter wheats case, it increases the proportion of unsaturated phospholipids in the membrane. This is especially when the the winter comes and this mechanism helps it remain fluid during the winter season.
