Answer the following question given this paragraph: 

Figure below shows how phospholipid molecules are arranged in a cell membrane. One end (the head) of each phospholipid molecule is polar and attracts water. This end is called hydrophilic ("water loving"). The other end (the tail) is nonpolar and repels water. This end is called hydrophobic ("water hating"). The nonpolar tails are on the inside of the membrane. The polar heads are on the outside of the membrane. These differences in polarity allow some molecules to pass through the membrane while keeping others out. You can see how this works in the video at the URL below.


Q: The end of the phospholipid molecule that is polar and attracts water is called what?

 Choices:

- cytosolic

- hydrophobic

- magnetic

- hydrophilic
