Sieve tubes

Vedclass · Answer

(C) The correct answer is $C$. Sieve tubes are living cells that lack a nucleus at maturity but retain a thin layer of cytoplasm and a plasma membrane. Because they are living and lack thick secondary lignified walls (unlike vessels,tracheids,or fibres),their cell walls are more extensible and flexible to facilitate the transport of food materials.

Which of the following cells have more extensible walls?
