What is one of the ways that the membranes of winter wheat are able to remain fluid when it is extremely cold?

Winter wheat is vital for provision of crops outside peak season especially for heifers. Winter wheat is the most popular arable crop but it suffers greatly from low temperatures. The membranes must be kept fluid if the crop is to succeed.

Many plants can adapt to temperature changes by altering the ratio of unsaturated to saturated fatty acids within their cell membranes. In the case of winter wheat, it increases the percent of unsaturated phospholipids as winter approaches. Therefore the option A amongst the answers is the correct one to choose.
