Question

The only plant cells without nucleus among the following are

• A. Cambium cells
• B. Xylem vessels elements
• C. Root hairs
• D. Companion cells

Answer 1

The correct option is B Xylem vessels elements

There are many parts of plant which do not contain nucleus:

• Sclerenchymatous cells get deposited by lignin and lose nucleus & cytoplasm at maturity.
• Xylem vessels consist of series of elongated dead cells for quick conduction of water and salts.
• Sieve tubes which also conduct food, don't have nucleus in them.
• Dead cork cells which replace the epidermis in woody plants.

So, the correct answer is 'Xylem vessels elements.'
