Explanation Difference 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 Final Answer The main difference is that collenchyma are living cells and sclerenchyma are dead cells

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.
