Differentiate between Parenchyma, Collenchyma and Sclerenchyma on the basis of their Cell Wall

Updated on: November 14th, 2023

The Difference between Parenchyma, Collenchyma and Sclerenchyma based on their Cell walls is that in Parenchyma, the living cell and walls are flexible because of the thin-walled cells present in it, in Collenchyma, the living cells are irregular and thick-walled, and in Sclerenchyma, the thickened lignified wall is present, which gives strength and makes them waterproof. Tissue provides mechanical and structural strength and exhibits labour division. In a multicellular organism, organs comprise a group of tissues. Cells that make up simple tissues are similar in structure and function. They only contain one type of cell.

According to Cell Wall, the cells of parenchyma tissues are scattered throughout the tissues and have relatively thin cell walls. In collenchyma, the cell wall is unevenly thickened at the corners, and there is hardly any space between the cells. Sclerenchyma has thickened cell walls and no intercellular space evenly.

Parenchyma, Collenchyma and Sclerenchyma

The main difference between parenchyma cells, collenchyma cells, and sclerenchyma cells is that parenchyma cells are involved in photosynthesis, storage, and secretion. In contrast, collenchyma cells are involved in the support and transportation of nutrients, and sclerenchyma cells are engaged in the support, protection and transportation of water.

Every soft portion of a plant contains parenchyma cells. Sclerenchyma cells are present in mature plant tissue. Particular plant components, such as leaves and stems, contain collenchyma cells.

Difference between Parenchyma, Collenchyma and Sclerenchyma

The differences between parenchyma, collenchyma and sclerenchyma, based on their cell wall, are given here:




It has thin-walled living cells

It has thin-walled living cells

It has dead cells

Involved in food storage

Chief mechanical tissue in young plants, mostly in dicot stems

It is mostly a mechanical tissue.

Made up of cellulose and comprises a thin cell wall

Made up of hemicellulose and pectin and comprises of uneven cell wall

Made up of lignin and comprises a thick and hard cell wall

In addition to photosynthesis and storing cooked food, they are also helpful in gas trading.

Although it doesn’t engage in photosynthesis, it gives plants flexible and mechanical integrity to protect them from the wind and other environmental factors.

It enables the movement of water and nutrients through the xylem and phloem, giving the plants mechanical stability.

These live cells may be discovered in the tender regions of the plant body and the young.

They are live cells that may be found in the petioles, juvenile stem segments, and leaves.

Only the mature sections include these dead cells.


Differentiate between Parenchyma, Collenchyma and Sclerenchyma on the basis of their Cell Wall.

The major difference between Parenchyma, Collenchyma, and Sclerenchyma based on the cell wall is that the parenchyma contains thin-walled cells, whereas live cells have flexible walls. Collenchyma is made up of irregularly shaped living cells with strong walls. Sclerenchyma cells have lignified walls which have formed, providing them strength and protection. Parenchyma cells provide photosynthesis, gas exchange, and food storage. The plant’s flexibility and mechanical support are provided by collenchyma cells. The mechanical structure of the plant is supported by sclerenchyma cells.
