across from the cones to the needles down from the needles to the roots up from the roots to the branches circular from the top to the bottom of the trunk
I gave my students this multiple choice question: In which way are sugars usually transported throughout a pine tree?

Only one answer is correct among these 4 choices:
- across from the cones to the needles
- down from the needles to the roots
- up from the roots to the branches
- circular from the top to the bottom of the trunk

Could you tell me which one is correct?
