  Dwarf galaxies constitute 18\% of the galaxies in the core of the Coma
Cluster. We present the correlation between structural properties and
morphology of galaxies in the central region of Coma Cluster for 221 objects
within the apparent magnitude range m $<$ 19.5. The data is taken from the
HST/ACS Coma Cluster Treasury Survey. For cluster membership we have used
photometric redshifts and spectroscopic redshifts from literature. From the
investigation of correlations of effective radius, Sersic index, absolute
magnitude and bulge to total light ratio, we find the galaxies are distributed
as follows: dwarfs 18\%, E/SO 33\%, SO 22\%, Sb \& Sb0 17\% and 10\% are
Spirals+Irregulars+Ring. We found that multiple component fits are best for
giants and the single Sersic fit is best for dwarfs \& spiral galaxies. We
shall try to explain why the single Sersic fit is best for dwarfs and what kind
of stellar orbits do they correspond to using the bulge Sersic index of dwarfs .
