Answer:
Fatty acids have a carboxyl group at one end of a hydrocarbon molecule. 
<u>The carbon atoms in saturated fatty acids are linked entirely by single C-C bonds.</u>
Unsaturated fatty acids contain one or more double bonds.
<u>Double bonds cause molecules to bend, and they can pack less tightly.</u>
 
        
             
        
        
        
Body cells are those that are responsible for the formation of tissues and organs, while a gamete is that cell responsible for reproduction.
- Gametes are sex cells, when a male gamete joins a female gamete in the framework of sexual reproduction of plants and animals, a zygote is formed.
- Body cells are any cell in the body that are not gametes, which originate from embryonic stem cells and constitute the totality of the body's tissues and organs of multicellular organisms.
Therefore, we can conclude that body cells are those cells responsible for the growth of organs and tissues and gametes are each of the sex cells that fuse during fertilization.
