1.	A common characteristic feature of plant sieve tube cells and most of mammalian eryhrocytes is cells and most of mammalian erythrocytes isA. absence of mitochondriaB. presence of cell wallC. presence of hemoglobinD. absence of uncleus.
Answer» Correct Answer - D The mammalian RBCs lose their nuclei at maturity and survive for a few months only. The food conducting phloem cells called sieve tubes, of flowering plants also lose their nuclei at maturity but they remain functional for several years.
