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.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
