Question

List the difference between Paranchyma, Collenchyma and Sclerenchyma based on cell wall structure and function.

(I'm giving 20, points only quality content)

Answer 1

Hii there!!!

Paranchyma tissue-
1) It consists of relatively unspecialised cells with rhin cell walls.
2) The cells are lossely packed so that large intercellular spaces are found in this tissue.

Collenchyma tissue-
1) The flexibility in plants is due to collenchyma tissues.
2) The cells of this tissue are living, elongated and irregularily thickened at the corners.

Sclerenchyma tissue-
1) The cells of this tissue are long and narrow as the walls are thickened due to lignin.
2) Often these walls are do thick that there is no intercellular space between them.

Hope it helps....

Answer 2

Hey!

_______________

Based on Cell wall structures Parenchyma, Sclerenchyma and Collenchyma could be dIfferentiated as :-

● Parenchyma :-

The cell walls of parenchyma are thin walled and are composed/made up of Cellulose.

● Collenchyma :-

The cell wall of Collenchyma are thickened due to the deposition of Lignin.

● Sclerenchyma :-

The cell walls of Sclerenchyma are thickened only at corners due to the deposition of Pectin.
