Question

Plants in hilly areas have to bear high-speed winds and coldness. Which of the following adaptation(s) help them face the above conditions?

• A. Having lots of branches and leaves
• B. Leaves which are modified into spines
• C. Breathing roots which come above the ground
• D. Tall and straight trunk with needle like leaves

Answer 1

The correct option is

C

Tall and straight trunk with needle-like leaves

The trees that grow in hilly areas have needle-like leaves, which are very tough and can survive in cold conditions and wind. Needle-like leaves do not allow the snow to cling to the leaf. The trees form a waxy substance on their leaves that seals moisture in, due to the fact that thin soil in the mountains cannot retain moisture. Also, plants in the far north or high on mountains grow close to the ground in order to protect themselves from the wind.
