Question #6a16f

1 Answer

continuity of channels.

Explanation:

  1. The vessels of the xylem and tubes of the phloem or sieve tubes are the channels of translocation of sap/water and food to their sinks.
  2. The vessels of the xylem have continuous channels like an open tube, while the tubes of the phloem are not an open tube like continuous channels. The tubes of the phloem are interconnected by special pores i.e., sieve tubes. The sieve tubes control the rate of flow. Thank you
