Gwhich of the statements are true? a plant that produces more monounsaturated fatty acids than polyunsaturated fatty acids in its membranes in winter has an increased resistance to freeze damage. cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties. cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids. yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.

Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.

Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.

Explanation:

The organisms which live in cold environment must have more amount of unsaturated fatty acids as compared to saturated fatty acids because unsaturated fatty acids tend to freeze at comparatively lower temperature which provides the organisms an advantage and better adaptability to live in such environments. The unsaturated fatty acids will not freeze easily even in cold environment and their body/cell will keep working perfectly even in cold weather. In contrast to this, the saturated fatty acids will freeze easily and the whole system of that organism will collapse during winter season.

Same goes with yeast. more unsaturated fatty acids in the body as compared to saturated fatty acids will help the yeast to live in cold environment. The reason for better adaptability is same as above.
