Question

Which of the following structure is responsible for transportation of water in higher plants?

• A. Companion cell
• B. Sieve cell
• C. Vessel
• D. Sieve tube

Answer 1

Answer: (C)

Vessel

In higher plants, water transportation is done by xylem tissue. Xylem consists vessels, tracheids, xylem parenchyma and xylem fibres. Vessels and tracheids are responsible for water conduction due to transpirational pull and root pressure. xylem fiber gives mechanical strength to the xylem and parenchyma stores nutrients and helps vessels in conduction. Whereas companion cells, sieve cell and sieve tubes are the components of phloem that helps in conduction of food in plants. Thus, the correct answer is option C.
