Translocation

Phloem tissue transports dissolved sugars from the leaves to the rest of the plant.

Is phloem transport one-way or two-way?

What is Translocation?

"Translocation is the movement of dissolved sugars from the leaves to other parts of the plant via the phloem."

Sugar Transport in Plants

Phloem tissue: Transports dissolved sugars (sucrose) from leaves to growing and storage organs.

Bidirectional: Movement can be both upwards and downwards in the plant.

Tubes: Phloem is made of elongated cells with pores in the end walls (sieve plates).

Importance: Provides energy for growth and storage (as starch).

Exam Tip

While xylem transport is one-way, phloem transport (translocation) is two-way.
