Vedclass · Answer

(A) Phloem loading is the process of transporting sugars from the source (usually leaves) into the sieve tube elements of the phloem. This process involves the active transport of sucrose into the sieve elements,which increases the solute concentration inside the phloem. As a result,water enters the phloem from the adjacent xylem by osmosis,creating a high turgor pressure that drives the bulk flow of sap towards the sink.
