. Differentiate between Collenchyma and sclerenchyma
Consists of living cells that have thickened at the corners by
the deposition of cellulose, hemicellulose, and pectin.
Consists of dead cells without protoplasts.
These cells have thick and lignified cell walls having few or many pits.
Pits can be simple or branched.
|They may be oval, spherical, or polygonal in shape.||
Sclerenchyma may be either fibres or sclereids.
Fibres are elongated and pointed and occur in groups.
Sclereids are spherical, oval, or cylindrical with narrow lumens.
|Mechanical support is provided to the growing parts of the plant.||It provides mechanical support to organs.|
The main difference is that collenchyma are living cells and sclerenchyma are dead cells.
