Chapter 3, Problem 1TC
Nutritionists advise us to avoid consuming oils from tropical plants because, compared with oils from temperate plants, they contain high levels of saturated fatty acids. Let’s try to determine a physiological reason for this difference in fatty acid composition.
Change in Plasma Membrane Linolenic Acid Content of Seedlings
Weeks of Exposure to Chilling (5°C)
- Linolenic acid is an unsaturated fatty acid. What structure does an unsaturated fatty acid take? What happens to its level following exposure of plants to cold temperatures?
- If you put a product with a high level of unsaturated fats (such as canola oil) and a product with a high level of saturated fats (such as butter) in your refrigerator (chilling temperature), how would they differ in consistency? Why?
- How might fatty acid composition relate to chilling tolerance in plants?

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forward
