Differentiate between parenchyma,collenchyma,and sclerenchyma on the basis of their cell wall.

(N/A) The differences between parenchyma,collenchyma,and sclerenchyma based on their cell walls are as follows:
$1$. $\text{Parenchyma}$: These are living cells with thin cell walls composed of cellulose. The cell walls are uniformly thin,and the cells are loosely packed with large intercellular spaces.
$2$. $\text{Collenchyma}$: These are living cells with unevenly thickened cell walls. The thickening is primarily due to the deposition of pectin and cellulose,specifically at the corners of the cells. They have very little intercellular space.
$3$. $\text{Sclerenchyma}$: These are dead cells with extremely thick,lignified cell walls. The deposition of lignin makes the walls rigid and impermeable to water. Due to this heavy thickening,the internal lumen (cell cavity) is often absent or significantly reduced.
