Of a plant carries sugar from the leaves to the roots

parenchyma

xylem
phloem
all of the above

The correct answer is the phloem

This is an odd question considering that the Xylem AND the Phloem delivers water, sugars and other important substances to the roots from the leaves. The answer is definitely NOT the Parenchyma, as that is a ground tissue in non-woody plants.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
