Question

give 3 pts of difference between - parenchyma, collenchyma and
sclerenchyma

Krishnakoli Datta · Accepted Answer

Parenchyma

Collenchyma

Sclerenchyma

Very thin cell wall

Unevenly thickened cell wall

Thick cell wall

The cells are loosely packed

Little space between cells

No intercellular spaces present, cells are tightly
packed

The cell wall is made up of cellulose

The cell wall is made up of hemicellulose and pectin

The cell wall is made up lignin

Most of the plant tissues are made up of parenchyma
cells

Collenchyma cells make up the epidermal layers

The outer woody stem portion of large trees is made up of
sclerenchyma cells

Cells are living

Matured cells are dead
