Research using carbon dioxide A, B, C
containing a radioactive label, C14,
has revealed the following
evidence about the mechanism of
translocation:
A- labelled carbon can be
observed in the phloem soon after
being supplied to a well-lit plant
B-the rate of movement of sugars
in the phloem is many times faster
than could be achieved by
diffusion alone.
Different research revealed that:
C-an insect such as an aphid feeds

by inserting its proboscis into the

State what is meant by the terms source-site where assimilates are loaded (into
source and sink. phloem)
sink-site where assimilates are
unloaded/removed (from phloem)
When the bark is removed from a -sugars can't pass the cut
tree, the phloem is also removed. If -decrease water potential
a complete ring of bark is removed, -water moves into cells
the tree trunk can be seen to swell -damage triggers increased cell division
about the cut. -to produce cells to store sugars
Suggest 2 reasons why the trunk -cut causes gall/infection
swells above the cut.
