Flowering plants are multicellular eukaryotic photoautotrophic flower producing
organisms. Their morphological features and traits are genetically determined. Even
though the angiosperms show such a large diversity in external structure, they are all
characterised by presence of roots, stems, leaves, flowers, seeds and fruits.
Morphology deals with the study of external forms and features of different plant
organs like roots, stem, leaves, flowers, seeds, fruits etc. It also study the variations in
different parts as adaptations to their environment for climbing, storage, protection etc.It
plays a key role in the classification of angiosperms (a-taxonomy).
