OpenStudy (anonymous):

hi. idk the answer to the Q but i need to ask you a Q.

OpenStudy (anonymous):

oh. I think it's carbohydrates.

OpenStudy (anonymous):

umm nice try but im pretty sure thats not it.. :)

OpenStudy (poopsiedoodle):

Leaves are the most common source for sugars in a plant because of their chlorophyll.

OpenStudy (poopsiedoodle):

<insert the rest of the explanation here>

OpenStudy (anonymous):

haha ok. yeah, poopsiedoodle's answer makes more sense.

OpenStudy (anonymous):

ooh thank you!! but... what is the rest of the explanation...

OpenStudy (anonymous):

is it because chlorophyll stores sugar??

OpenStudy (poopsiedoodle):

I'm looking it up right now.

OpenStudy (anonymous):

doesnt chlorphyll create sugars during photosynthesis and that's why leaves contain sugar?

OpenStudy (poopsiedoodle):

It's because chlorophyll is the main ingredient in photosynthesis, which produces glucose.

OpenStudy (anonymous):

OK SOO THIS IS THE PARAGRPAH I HAD TO READ AND THAT WAS THE QUESTION- the pressure-flow model explains how sugars from photosynthesis move through the plant within the phloem. Phloem sap moves from a sugar source to a sugar sink. A source is any part of the plant that has a high concentration of sugars. Most commonly this source is the leaves, but it can also be where sugars have been stored, such as the roots. A sink is the part of the plant using or storing the sugar, such as growing stems, a fruit, or even the storage roots that will be a sugar source later in the season. The locations of sugar sources and sinks in a plant can change as the plant grows and as the seasons change.
