A common characteristic feature of plant sieve tube cells and most mammalian erythrocytes is
1.
absence of mitochondria
2.
presence of cell wall
3.
presence of haemoglobin
4.
absence of nucleus
The common characteristic feature of plant sieve tube and mammalian erythrocyte the absence of nucleus. Sieve tubesare the component of phloem and do not conta nucleus. Similarly, erythrocytes in mammalian cell also do not posses nucleu Erythrocytes are the RBCs which helps in gaseous exchange.
Mitochondria is absent in sieve tube cells. ‘Pigment haemoglobin is present mammalian erythrocytes but not in sieve tube cells. Cell wall is made of cellulose and present in all plant cells, and thus absent in erythrocytes.
