I need help on the following questions, I am not understanding the
concept!
1. The 4 classes of macromolecules of living organisms are
- carbohydrates
- lipids
- nucleic acid
- proteins
What does this mean, I do not understand it!!
2. Does plants store their fats as oil or starch? Carbohydrates play a
role in this but as which ones or is it both??
3. Phospholipids are some kind of fat for plants? Is it an wax or what??
4. How come water and oil do not mix? I don't understand the part about
the polar and non-polar bondings
