Membrane lipids of chill-sensitive plants contain
-
- low proportion of saturated fatty acids.
- low proportion of unsaturated fatty acids.
- equal proportion of saturated and unsaturated fatty acids.
- high proportion of unsaturated fatty acids.
- low proportion of saturated fatty acids.
Correct Option: D
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.
