Question

if osmotic pressure in sink cells is reduced then, why active transport of sugar is needed to move sugars out of the phloem sap into sink cells?

Answer 1

Answer:

At the sink, osmotic pressure must be reduced. Again active transport is necessary to move the sucrose out of the phloem sap and into the cells which will use the sugar converting it into energy, starch or cellulose. As sugars are removed, the osmotic pressure decreases and water moves out of the phloem.
