Vedclass · Answer

(C) The movement of sugars in the phloem begins at the source,where sugars are loaded into the sieve tubes via active transport. This increase in solute concentration lowers the water potential inside the sieve tube,causing water to move from the adjacent xylem into the phloem by osmosis. This influx of water increases the hydrostatic pressure,also known as turgor pressure,within the sieve tube,which drives the mass flow of sap from the source to the sink.

When sugars enter sieve tubes,water flows by osmosis,resulting in:
