Question text

Oils at room temperature are liquid. The table below indicates typical composition of saturated fats from different plant sources.

Both coconut and palm oil are tropical oils, the plants are native to tropical climates. Canola was bred originally in Canada, and olive trees are native to the Mediterranean basin.

Analyze the possible relationship between saturated fat levels and geography. Which of the following explanations is most plausible?

Select one:

The warmer temperatures in tropical climates break double bonds in unsaturated fats, saturated fats are more stable in membranes.

In climates with cooler temperatures, plants need higher levels of saturated fats to maintain membrane fluidity.

Because saturated fats have kinks at double bonds, membranes are more fluid at lower tempertures found in cooler climates.

Plants in colder temperatures in northern climates cannot maintain sufficient membrane fluidity with high levels of saturated fats.

Explanation / Answer

In climates with cooler temperatures, plants need higher levels of saturated fats to maintain membrane fluidity.
