It is present in plant cell but absent in animal cell.

Examine the figure:
$(a)$ Is this structure present in an animal cell or a plant cell?
$(b)$ Can these be passed on to the progeny? How?
$(c)$ Name the metabolic processes taking place in the regions marked $(A)$ and $(B)$.

$A$: Chloroplast is a semi-autonomous organelle.
$R$: The ribosomes of the chloroplast are smaller than cytoplasmic ribosomes.
