Answer 1

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 hemicelluloses and pectin.

The cell wall is made up lignin.

Most of the plant tissues are made up of parenchyma cells.

Collenchymas cells make up the epidermal layers.

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

Cells are living.

Cells are living.

Matured cells are dead

Answer 2

Parenchyma
1. It have large thin walled cells which are oval cellular or polygonal in shape.
2. Found in soft part of the plant such as in cortex and in the pith.
3.Provide temporary support to the plant and also serve as food storage in potatoes.



Collenchyma

2. It is found in the leave stalks and below the epidermis of stem.
3. It tissue help to support the part of the plant.
