Question

Read the description below.

Another way that plant systems and tissues work together is in the transport of materials such as food, called translocation. Auxins are plant hormones produced in the parenchyma. For a plant to grow, certain auxins move through the phloem to the cells of the collenchyma ground tissue in the apical meristem. These auxins tell those cells that they need to divide. In order to do this, those cells need the sugars transported from the leaves through the phloem vascular tissue.

Which of the following tissues and systems were involved in translocation? Check all that apply.

roots

stem

leaves

dermal tissue

vascular tissue

ground tissue

Answer 1

Select: stem, leaves, vascular tissue, ground tissue.

Why: The sugars and auxins are moved through the phloem (vascular tissue) from the leaves (source) along the stem to target cells. The hormones originate in and act on parenchyma/collenchyma, which are ground tissues. Roots and dermal tissue are not mentioned as part of this translocation in the passage.
