Question

Which of the following statements is/are true?

a. Water moves through a tree mainly using the force of gravity.
b. Non-polar molecules would move up trees in the same way water does.
c. Water moves up a tree in tubes. These tubes must be polar.
d. All of these are true

Answer 1

Answer: Option D

Explanation:

Water is a polar molecule meaning that there is uneven distribution of electrons between the hydrogen atoms and oxygen atoms. The oxygen atom is electronegative and negatively charged and it attract more electrons while the hydrogen atoms is positively charged. For water to move up in trees in tubes, the tubes must be polar because water itself is a polar molecule.
