Vedclass · Answer

(C) In mature mammalian red blood cells $(RBCs)$,the nucleus is lost to provide more space for hemoglobin. In the xylem tissue,mature vessel elements are dead and lack a nucleus. In the phloem tissue,mature sieve tube elements lose their nucleus to facilitate the transport of food. Companion cells are specialized parenchyma cells that remain living and retain their nucleus at maturity to support the metabolic activities of the adjacent sieve tube elements.

Which of the following does not lose their nucleus at maturity?
