Collenchyma tissue is a type of simple plant tissue that consists of living cells with thickened cell walls. These thickened cell walls provide structural support and flexibility to the plant. Collenchyma cells are elongated and have irregularly thickened corners, giving them a polygonal shape.
The primary function of collenchyma tissue in plants is to provide mechanical support to growing plant parts, such as stems, leaves, and petioles. Collenchyma cells are particularly important in young, growing plant tissues where they help to maintain the shape and structure of the plant. They also provide flexibility, allowing the plant to bend without breaking in response to environmental factors such as wind or physical stress.
In addition to their structural role, collenchyma cells can also serve as a storage site for nutrients and water, and may play a role in wound healing and defense against pathogens. Overall, collenchyma tissue plays a crucial role in the growth and development of plants, helping them to withstand external pressures and maintain their structural integrity.

Collenchyma Tissue
Collenchyma is a plant tissue characterized by its thick, flexible cell walls that provide structural support.
Structure:
- Composed of elongated cells with irregular shapes and thickened cell walls at the corners.
- Cell walls contain cellulose, hemicellulose, and pectin.
- Cells have living protoplasts (cell contents) with large central vacuoles.
Function:
- Provides structural support to growing plant parts and young stems.
- Allows flexibility and elasticity, enabling plants to withstand bending and mechanical stress.
- Protects against environmental stress, such as wind and gravity.
- Supports and guides the growth of new tissues and organs.
Locations:
Collenchyma tissue is typically found in:
- Stems (just beneath the epidermis)
- Petioles (leaf stalks)
- Flower stalks
- Edges of leaves
- Around vascular bundles
Types:
There are two main types of collenchyma:
- Angular collenchyma: Cells have sharp corners and thickened cell walls at the angles. Found in stems and petioles.
- Lamellar collenchyma: Cells have flattened walls parallel to each other. Found in leaf blades and flower stalks.
Importance:
Collenchyma tissue is crucial for the growth and development of plants. It provides essential structural support, enabling plants to stand upright, withstand environmental forces, and transport water and nutrients efficiently.
