Question:

Tracheids are

Options:

1. Elongated cells with tapering ends and unperforated end walls
2. Elongated cells with tapering ends and perforated end wall
3. Rounded cells with lignified walls
4. Both 1 and 2

Solution:

Tracheids are elongated cells with tapering ends and unperforated end walls. Tracheids are a type of water-conducting cells found in the xylem tissue of vascular plants. They are characterized by their long, thin shape and their lack of perforations in their end walls. The tapering ends of the tracheids overlap with each other, forming a continuous network of water-conducting channels. Option 1 correctly describes the structure of tracheids. Option 2 is incorrect as tracheids do not have perforated end walls. Option 3 is incorrect as rounded cells with lignified walls are not tracheids, but sclereids or fibers that provide mechanical support to the plant.
