In Which Direction Would Translocation Occur in a Pine Tree

Question

In which direction would translocation occur in a pine tree?
A) from the roots to the needles
B) from pinecones to the roots
C) from the sugar source to the sink
D) from the sugar sink to the source

Accepted Answer

Translocation in a pine tree would occur from the sugar source, which is the needles, to the sugar sink, which is the rest of the tree. This is because the needles produce sugars, through photosynthesis, and the tree needs those sugars to grow and function. Therefore, the sugars are transported from the needles to the rest of the tree, which is the sink.
