Answers & Comments
Answer:
D) Root hair→vascular tissue→dermal tissue→stomata
Explanation:
Water is absorbed by the root hairs and then moves into the vascular tissue (xylem) which carries it upwards towards the leaves. From the xylem, the water moves into the leaf cells and ultimately evaporates through the stomata, which are tiny pores located on the surface of the leaves. Therefore, the correct order of water movement is from root hair to vascular tissue to dermal tissue and finally to stomata.
