Question

In angiosperms, xylem is made up of

• A. Tracheids and vessels
• B. Vessels and fibres
• C. Tracheids and fibres
• D. All the above

Answer 1

The correct option is D All the above

The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels. Xylem also contains two other cell types: parenchyma and fibers.

So, the correct answer is 'All of the above.'
