Answer 2

Answer:

Xylem elements contain the tracheids and vessels. These help in the conduction of water. They are long tube-like structures with partially or completely dissolved walls to form water pipes (in vessels) and pits in the cell wall (in tracheids) for conducting water.

Sieve tubes are slender tube-like structures with their end walls perforated by numerous pores and are called sieve plates. They are phloem elements and are the main food conducting elements.

Companion cells possess a perforated cell wall.

Therefore, the correct answer is option A.
