Question

What is the basic difference between collenchyma, parenchyma, and sclerenchyma?

Answer 1

Hint:The tissue is a group of similar or dissimilar cells that have the same origin and a common function to perform. Moreover, collenchyma, parenchyma, and sclerenchyma are the simple permanent types of tissue found in plants.

Complete answer:
The basic difference between the collenchyma, parenchyma, and sclerenchyma –

Collenchyma	Parenchyma	Sclerenchyma
It is the living tissue.	It is the living tissue.	It is the dead tissue.
The cell wall is made up of cellulose and hemicellulose.	The cell wall is made up of cellulose and pectin.	The cell wall is made up of lignin and cellulose.
The cell wall is thin and even.	The cell wall is thin and uneven.	The cell wall is thick.
Intercellular spaces are present.	Intercellular spaces are normally absent.	Intercellular spaces are absent.
It is associated with food storage.	It is a mechanical tissue that is responsible for providing mechanical strength and support to plants.	It is the chief mechanical tissue that is associated with providing mechanical strength to plants.
Most parts of the plant are made up of parenchyma cells. They are also found in the mesophyll tissue of leaves.	It is present in dicot stems just below the epidermis. It is known as hypodermis there. It is absent in roots and monocot stems.	It is present in xylem, phloem, the pulp of fruits, seed coat, endocarp of coconut, the pericarp of walnut.

Note: Permanent tissues are those tissues that are formed by the division or the activity of the primary and the secondary meristem. Simple permanent tissue is that tissue that is made up of similar kinds of cells. Apart from the simple permanent tissue, the permanent tissue is classified as complex permanent tissue and a secretory or special type of permanent tissue. The complex permanent tissue is made up of different kinds of cells.
