which plant organ transports substances up and down the plant?

The plant organ that transports substances up and down the plant is the phloem , which carries dissolved food (like sugars) both upward and downward through the plant.

Quick Scoop

• The phloem is a vascular tissue found mainly in the stem, but it also runs through roots and leaves as part of vascular bundles.

• It transports dissolved food substances (such as sucrose) from where they are made in the leaves to other parts of the plant, moving up and down depending on where they are needed.

• By contrast, xylem mostly moves water and mineral salts upwards only , from the roots to the rest of the plant.

So, for the question “which plant organ transports substances up and down the plant?” the correct answer is: phloem.
