Which is correct about the transport of conduction of substances?

Explanation

Phloem is the food-conducting tissue of plants. The sieve tubes are food-conducting elements of the plants. It is proposed that food is translocated by mass flow or by streaming currents of protoplasm. The movement of organic food materials or the solutes in soluble from one place to another in higher plants is called as translocation of organic solutes. Protoplasmic streaming occurs in sieve tube elements of phloem and the solute molecules caught up in the circulating cytoplasm are carried from one end to the other end of the sieve tube from where they diffuse to the next sieve tube elements through the cytoplasmic strands in the sieve plates.
