Differentiate between sclerenchyma and parenchyma tissues. Draw well labelled diagram.
The differences between sclerenchyma and parenchyma tissues are:
Parenchyma |
Sclerenchyma |
It consists of living cells |
It consists of dead cells |
It consists of thin-walled cells |
Its cell walls are uniformly thickened. |
The cell wall is made up of cellulose |
The cell wall is made up of a complex polymer called lignin |
It serves as packing tissue |
It serves as mechanical tissue |
It stores food and performs photosynthesis |
It gives strength, and rigidity and protects from the attack of parasites. |
