Differentiatebetween parenchyma, collenchyma and sclerenchyma, on the basis oftheir cell wall.
Parenchyma | Collenchyma | Sclerenchyma |
Cell walls are relatively thin, and the cells in parenchyma tissues are loosely packed. | The cell wall is irregularly thickened at the corners, and there is very little space between the cells. | The cell walls are uniformly thickened, and there are no intercellular spaces. |
The cell wall in this tissue is made up of cellulose. | Pectin and hemicellulose are the major constituents of the cell wall. | An additional layer of the cell wall composed mainly of lignin is found. |
