Step 1
Suggest which vessel could transport the herbicide from the leaf to other parts of the plant.
Answer
The vessel that could transport the herbicide from the leaf to other parts of the plant is the phloem.
Phloem is responsible for the transport of nutrients, including sugars and signaling molecules, throughout the plant. The herbicide, once absorbed by the leaves, would dissolve in the phloem sap and be distributed to other regions, allowing for effective herbicide action throughout the plant.
