Background and context

Parenchyma cells forms the most of the plant body and they are living in nature and has the ability of division. The cells of parenchyma are rounded or isodiametric, i.e., from all the sides they are equally expanded. The cells of parenchyma are oval, round, polygonal or elongated in shape. The cell wall of parenchyma cell is thin and encloses a dense cytoplasm.

The parenchyma cell is widely present in such as stem, roots, leaves, flowers and fruits of the plant bodies. Thus, the parenchyma cells are found in the soft parts of the plant such as cortex of roots, ground tissues in stems, etc.
