Why does water roll off the surface of a leaf a. because the leaf hydrogen bonds with the water b. because water is a nonpolar molecule c. because leaves don't contain starch d. because the surface of the leaf is nonpolar

Hello!

The answer is D.) Because the leaf is coated in lipid molecules

A is wrong because water is polar, an example of non polar is oil, and everyone knows that oil and water do not mix. Their molecules just aren't attracted to each other.

B is wrong because water is polar.

C is wrong because cellulose is one of the most abundant organic compounds on the Earth, and it's a major component of the cell walls in plant cells.

Because the surface of a leave is nonpolar. I just did it!

Explanation:

All the others ARE WRONG except for this one.

Just like when you step out of a swimming pool, why does the water roll off your body? Part of the answer is that your skin is made of cells that are covered in lipids. Lipids do not mix with water because water is made of polar molecules, and lipids are nonpolar molecules.

Ever heard the word hydrophobic? Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic. A leaf is nonpolar! Water is polar! They don't dissolve...

This is correct and true! But before submitting an answer make sure the question is the same one. Stay Safe!
