What is Collenchyma
Collenchyma is a cellular tissue which, along with parenchyma, composes the bulk of plant tissues.
Unlike parenchyma, collenchyma cells are living cells. They have cellulose cell walls and are filled with water – which helps the plants to keep their shape.
Collenchyma cells also contain flatter chloroplasts than parenchyma cells and they give plants elasticity and rigidity by joining together to form fibers in bundles or bundles in strips throughout the plant’s body.
What are Collenchyma cells made of?
Collenchyma cells are made of strong, thick cellulose strands twisted around each other and cemented together. They have the ability to store water and can swell up to 200% when they absorb water.
Collenchyma cells are constantly growing in plants, which is why they are found on the outside of roots and stems. These cells allow plants to grow as they provide support for all other tissues and help with water absorption.
Roles and Function of Collenchyma Cell in Plants
Collenchyma cells are found in the secondary phloem of plants. Functions of these cells include: protection of the plant against mechanical injury, provide support for the vascular tissue, and act as a sheath that regulates water flow.
Significance of Collenchyma in the Plant Tissue
The collenchyma cells play an important role in the plant tissue because they help to provide structural support for the plants.
The collenchyma cells are thin-walled, elongated cells that have a small amount of cytoplasm and lack large vacuoles. They are usually found between bundles of vascular tissues or around the outside of vascular bundles.

- Unlike parenchyma cells, collenchyma cells are living. They have cellulose walls and water inside which help the plant keep its shape
- Collenchyma cells are found on the outside of roots and stems (secondary phloem)
- Major functions of collenchyma include protection of the plant against mechanical injury, provide support for the vascular tissue, and act as a sheath that regulates water flow.
Frequently Asked Questions on Collenchyma
What is Collenchyma?
Collenchyma is a tissue found in plant cells that help provide support and protection. It is considered part of the ground tissue (parenchyma) and it plays an important role in plants.
What is the function of Collenchyma?
Collenchyma helps to provide strength to the plant’s stems, branches, leaves, and other structures. This strength allows plants to grow up without breaking from the weight of their own body. Collenchyma also provides a protective layer for plants that contains water-holding cells called hydrochomes. This helps to prevent water loss through the plant’s tissues when it is under drought conditions or when there is intense sunlight exposure from high-altitude regions.
