Membrane lipds of chill-sensitive plants contain

Options

A. low proportion of saturated fatty acids
B. low proportion of unsaturated fatty acids
C. equal proportion of saturated and unsaturated fatty acids
D. high proportion of unsaturated fatty acids

Answer

D

Explanation

The membranes of chill sensitive plants have been found to have about a 2:1 ratio of unsaturated to saturated fatty acids. It has been seen that the proportion of unsaturated membrane fatty acids increases and the critical temperature decreases when chill sensitive plants are acclimated to a low temperature.
