Question

Unlike roots, stems

Answer 1

Inside the stem are xylem and phloem they transport food and water so I believe the answer is A

Answer 2

The correct answer is option A, Transport Water

Reason -

The stem consists of vascular tissues that have both Xylem and Phloem which are responsible for transporting water and food respectively. However, roots take in water  and mineral from soil through the process of diffusion and therefore its mode of transportation is different from that of stem.

Ground tissues and epidermal cells are found in both root and stem and none of them plays a direct role in photosynthesis.
