Vessels are part of which of the following plant tissue?
I. Xylem
II. Phloem
Show answer & explanation
Correct answer: A
Explanation
Xylem -
The tissue responsible for transporting water and minerals in plants is called xylem, and vessels are a major part of it.
Structure of Xylem -
Xylem is a complex permanent tissue composed of four types of cells:
Vessels: These are long, cylindrical, tube-like structures stacked one above the other. Their cell walls are made of lignin and are dead cells.
Tracheids: These also help in water conduction, but their structure is slightly different from that of vessels (pointed at the ends).
Xylem Parenchyma: These are the only living cells that store food.
Xylem Fibers: These primarily provide mechanical support to the plant.
