Differentiate between parenchyma collenchyma

Question

Physics Wallah · Accepted Answer

Explanation S No Parenchyma Collenchyma Sclerenchyma 1 The cell wall is commonly thin Extra thickenings in some places at tangential angles walls Highly thick walled cells with little or no protoplasm 2 Thickness is uniform Uneven thick cell wall Thickening is uniform 3 Cell wall is made up of cellulose Thickening consists of hemicellulose and pectin Thickening can be of cellulose lignin or can be of both 4 Consist of living cells Consists of living cells Made up of dead cells 5 Used for storage Provides mechanical strength and elasticity Provide mechanical strength only Final Answer Parenchyma collenchyma and sclerenchyma are simple permanent tissues Both parenchyma and collenchyma contain living cells whereas sclerenchyma contains dead cells

S.No	Parenchyma	Collenchyma	Sclerenchyma
1	The cell wall is commonly thin.	Extra thickenings in some places (at tangential angles, walls)	Highly thick-walled cells with little or no protoplasm.
2	Thickness is uniform.	Uneven thick cell wall.	Thickening is uniform.
3	Cell wall is made up of cellulose.	Thickening consists of hemicellulose and pectin.	Thickening can be of cellulose, lignin, or can be of both.
4	Consist of living cells.	Consists of living cells.	Made up of dead cells.
5	Used for storage	Provides mechanical strength and elasticity	Provide mechanical strength only.
