Question

Difference between parenchyma collenchyma schelernchyma

Answer 1

Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin

Answer 2

Answer:

Explanation:

Parenchyma:- Large thin walled cells,oval,circular or polygonal in shape

                     .  Usually a single large vacuole

                    .Found in soft parts of plants,such as in the cortex(outer region)   and in the pith (central region)            

                    .  Provide Temporary support to the plant

                     .  May store food as in potatoes

Some parenchymatous cells,particularly in the leaf,contain choloplast and are termed chlorenchyma(chloros : green). chlorenchyma helps the leaf to produces food by photosynthesis

Collenchyma(collen : glue):-   Made up of cell which elongated and the cell wall is thickened at the corner.It is found in the leaf stalks and below the epidermis of the stems.The tissues helps to support the parts of a plant.

Schelernchyma(scleros : hard):- Composed of long,narrow cells,which have become dead. These cells develop very thick walls due to the deposition of lignin. This tissues provides strength to plant parts.It is found in stems and veins of the leaves
