| Q. |
Membrane lipids of chillsensitive plants contain - |
| 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. high proportion of unsaturated fatty acids. | |
|
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. |
