Question

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

Answer 1

The cells of parenchyma are thin walled in structure and made of cellulose.

The cell walls thickened at the corners due to pectin deposition.

Parenchyma -

1)it has a primary cell wall

2)cell walls are thin

3)cell wall is made up of cellulose…

Collenchyma-

Cell walls of this tissue are thickened at te corners due to pectin deposition-

1)it also has a primary cell wall.

2)cell walls are thick at corners.

3)cell wall is made up of cellulose….

Sclerenchyma-

Wall of this cells are thicked due to pectin deposition.

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

✴️parenchyma
generally oval-shaped
thin cell wall
single vacuole
nucleus present
spaces found


colanchyma
generally alogated shaped
thick cell wall
small vocoule
nucleus present
mostly absent



sclerenchyma
generally angularshaped
thick cell wall vacuole absent
nucleus present
lacking
