Vedclass · Answer

(A) The $Sieve$ $tube$ $elements$ are specialized cells of the phloem tissue that lack a nucleus at maturity. They possess thin cellulosic walls and remain living despite the absence of a nucleus,as their metabolic functions are regulated by the adjacent companion cells. In contrast,$Cambium$ cells and $Phloem$ $parenchyma$ cells retain their nuclei throughout their functional life.
