Question

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

Answer 1

Answer:

Explanation:

Paranchyma - 1) it has a primary cell wall 

                    2) cell walls are thin 

                    3) cell wall is made up of cellulose

Collemchyma-1) it also  has a primary cell wall

                    2) cell walls are thick at corners 

                    3) cell wall is made up of cellulose

Sclerenchyma-1) it has a secondary cell wall  

                     2) cell wall is very thick reducing the cellular space of the                                 cell 

                     3) cell wall is made up of "lignin" 

Answer 2

Hii.. dude ..♥️

Parenchyma

• Cell wall is thin .
• Cell wall is made up of cellulose .
• It has a primary cell wall .

Sclerenchyma

• Cell wall is hard , rigid and very thick .
• Made up of lignin which is a water proof material .
• It has a secondary cell wall .

Collenchyma

• Cell wall is thick .
• Made up of cellulose and pectin .
• It has a primary cell wall .

hope this helps.....
