Question

Which is not a common feature in vessel elements and sieve tube elements ?

• A. Enucleate condition
• B. Presence of P-protein
• C. Thick secondary wall
• D. Pores on lateral walls

Answer 1

The correct option is A Enucleate condition

Phloem is a vascular tissue and its principal function is the conduction of food. It is composed of the sieve elements, of which two types can be distinguished, sieve cells and sieve-tube members. The vessels are nucleated whereas the sieve tube elements are enucleated.

So, the correct answer is 'Enucleate condition.'
