Vedclass · Answer

(A) The pressure gradient in the phloem is created by the loading of sucrose into the sieve tube elements. This process is facilitated by the companion cells,which actively transport sucrose into the sieve tubes. This creates a high osmotic pressure in the sieve tube,causing water to move from the xylem into the phloem,thereby generating a positive pressure gradient that drives the translocation of food.

Which structure of the phloem creates a pressure gradient in the sieve tube?
