Vedclass · Answer

(A) Mature human $RBCs$ (erythrocytes) lose their nucleus and other organelles like mitochondria and endoplasmic reticulum during maturation.This loss of organelles is an evolutionary adaptation to maximize the internal space available for hemoglobin,which is essential for the efficient transport of $O_2$ throughout the body.While they do not reproduce (as they are terminally differentiated) and are somatic cells,the primary functional reason for being enucleated is to increase the capacity for $O_2$ transport.Therefore,statement $(iv)$ is the most appropriate explanation.

Column-$I$ (Cells)	Column-$II$ (Percentage)
$P$. Neutrophils	$I$. $0.5-1.0\%$
$Q$. Eosinophils	$II$. $6-8\%$
$R$. Basophils	$III$. $2-3\%$
$S$. Monocytes	$IV$. $60-65\%$
$T$. Lymphocytes	$V$. $20-25\%$

Mature human $RBCs$ are enucleated. Which of the following is the most appropriate explanation for this?
$(i)$ They do not need to reproduce.
$(ii)$ They are somatic cells.
$(iii)$ They do not perform metabolism.
$(iv)$ Their internal space is available for $O_2$ transport.
