Solution
The correct option is B Trachea
Xylem tracheae are the integral component of xylem. These are also known as xylem vessels. They are generally present in higher angiosperms and these are involved in conduction. The tracheae are found arranged parallel to each other, extending from one end of the plant body to another. The tracheae are long cylindrical dead cells. They are characterized by a thick cell wall consisting of a primary wall and a secondary wall. The primary wall is made up of cellulose, whereas the secondary wall is made up of lignin. There is a spacious lumen that extends throughout the length of the trachea. The deposition of lignin in the secondary wall is not always uniform. As a result, the xylem vessels exhibit different types of secondary thickenings. Xylem vessels have perforation plates at their end walls, which are absent in other xylem elements. Thus, option B is correct.
