A typical angiospermic plant is sporophytic (2n) and has two well-developed systems, underground root system and above ground shoot system. The former consists of roots and their branches while the latter comprises of stem, its branches, leaves, buds, flowers and fruits. Out of these plant parts, root and stem are called plant organs, as they have their own embryonic initials, radicle and plumule, respectively. Root, stem and leaves are called vegetative parts as they take part in nutrition, growth and maintenance of plant body. Flower is considered as reproductive part because it is highly condensed and modified shoot meant for sexual reproduction. Fruit and seeds are reproductive products as they are produced after the completion of sexual reproduction.
