 Differentiate between Parenchyma and Sclerenchyma in a Tabular Form?

Asked by Anurag Mittal(DELHI PUBLIC SCHOOL) , on 4/7/13




The cells have thin cell wall.

The cells have very thick lignified cell wall.

The cells are alive.

The cells are dead at maturity.

They are block shaped.

They are elongated in shape.

Their primary function is to photosynthesize and storage.

Their primary function is to provide strength and support.

These tissues are present in the newly divided parts of plants.

These tissues are present in the older parts of a plant or tree.

The structure of these cells is roughly spherical, through some may be elongated.

The main function of parenchyma is to act as a packing tissue, it provides support in herbaceous plants.

These cells are metabolically active and are the sites for many of the vital activity of the plant body.

The air spaces between the cells of these tissue allow gaseous exchange to take place between the living cell and the environment.

Parenchyma is distributed in Cortex, pith, medullary rays in wood and as packing tissue in xylem and phloem.



The structure of these cells are roughly spherical, although it may vary considerably in size and shape, the primary cell wall is thickened with the deposits of lignin.

Their main function is to provide mechanical support and are most commonly found in the cortex, pith phloem, fruits and seeds.
