Tracheid is part of which plant tissue?
Show answer & explanation
Correct answer: A
Explanation
Tracheids are an essential component of the plant tissue known as Xylem. Xylem is a complex permanent tissue responsible for the vertical transport of water and minerals within plants.
Tracheids are long, narrow, and dead cells characterized by walls thickened due to lignin, which also provides mechanical support to the plant.
Their primary function is to transport water from the roots to the leaves.
In addition to tracheids, xylem also contains vessels, xylem parenchyma, and xylem fibers.
This tissue serves as the structural backbone of vascular plants.
Therefore, Option (A)—Xylem—is the correct answer.
