Why do roots sink sugar?
A root growing through the soil can’t do photosynthesis. The embryo requires sugar to grow however it can’t make it for itself. So it’s a sink for sugar and has low turgor pressure. Enzymes break down the starch kept in the seed transforming it to sugars.
Why does sink decrease osmotic pressure?
At the sink osmotic pressure need to be lowered Once again active transportation is needed to move the sucrose out of the phloem sap and into the cells which will utilize the sugar transforming it into energy starch or cellulose. As sugars are eliminated the osmotic pressure reductions and water vacates the phloem.
