Question

List two difference between parenchyma and sclerenchyma

Answer 1

Parenchyma is the most common type of unspecilalised simple tissue. It is composed of collection of cells which are more or less isodiametric in shape with or without intercellular space. These are the living cells with active protoplast.


Collenchyma The cells of this tissue are living cells with vacuolated protoplast. The most important distinctive character of collenchyma is that either walls are unevenly thickened or these thickenings are confined to the corners of the cells. It is usually absent in monocot.
