Solution:
The given figure shows the stages in embryogenesis
in a typical dicot (Capsella). The structure marked as A, B,
C and D is respectively suspensor, radicle, plumule and
cotyledon. Suspensor is a suspending part or structure as a
group or chain of cells that is produced from the zygote of a
seed plant and serves to push the developing embryo into
the endosperm. Radicle is the part of a plant embryo that
develops into the primary root. Plumule is the young shoot
of a plant embryo above the cotyledons, consisting of the
epicotyl and often of immature leaves. Cotyledon is an
embryonic leaf in seed-bearing plants, one or more of which
are the first leaves to appear from a germinating seed
