Question

The direction of movement of phloem sap in the phloem is _____ (a) Unidirectional (b) Bidirectional (c) Random (d) None of them

Answer 1

bidirectional is correct answer

Answer 2

"(b) Bidirectional

Movement of phloem sap in the phloem is bidirectional, that is, it moves in the opposite directions simultaneously. The sap contains nutrients which are transported to the growing tips of the plants and thus, it has to move upwards to reach the stem tips and young leaves and also downwards to reach the root tips. In growing seeds, the nutrients are transported in the upwards direction."
