Answer 1

Differentiate between Parenchyma, Collenchyma and Sclerenchyma on the basis of their cell wall.

Parenchyma	Collenchyma	Sclerenchyma
These are living cells with thin walls.	These are living cells with slightly thick walls.	These are dead cells with thick cell walls.
Cells are uniformly thin.	Cells are elongated.	Cells are long and narrow.
The cells are loosely packed with large intercellular spaces.	The cells are irregularly thickened at the corners with very little intercellular spaces.	The cells are thickened due to lignin. These are so thick that there is no internal space inside the cell.
