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.
Cells are living.
Matured cells are dead.

Here is your answer
Collenchyma:
1. The tissues consists of cells having localised thickening in their cell walls.
2. It occurs mostly in the aerial parts of the plants and is restricted to the other layers.
3. Collenchyma is the chief mechanical tissue in parts of a young plants particularly in the young dictyoledonous stems.
Parenchyma:
1. The tissue consists of thin-walled loving cells.
2. It is distributed in almost all the parts of the plant body.
3. The living cells of Parenchyma assimilate and store food. They also store waste products.
....Hope it helps!
