Question

Read the description below.

One of the ways that plant systems and tissues work together is in the transport of materials such as water, called transpiration. In transpiration, water is taken into the plant and then evaporates out of the leaves. First, water is taken in through pores in the dermal tissue of the roots and brought to the xylem of the vascular tissue. The vascular tissue then transports it up through the stem and into the leaves. Once in the parenchyma cells of the ground tissue of the leaves, photosynthesis and cellular respiration occur, using that water. The water is then released through guard cells of the dermal tissue into the atmosphere.

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

roots

stem

leaves

dermal tissue

vascular tissue

ground tissue

Answer 1

All of them — roots, stem, leaves, dermal tissue, vascular tissue, and ground tissue.

Briefly: roots (dermal tissue) take up water; vascular tissue (xylem) transports it up through the stem to the leaves; ground tissue (parenchyma) in the leaves uses the water; and dermal tissue (guard cells) releases it to the atmosphere.
