Collenchyma tissue provides flexibility and mechanical support to various parts of a plant, such as tendrils and stems of climbers, by allowing bending without breaking. It is typically found in leaf stalks below the epidermis.
What is the function of collenchyma tissue in plants, and where is it typically found?

Collenchyma tissue in plants provides structural support and flexibility. Its primary function is to lend strength to young, growing plant parts. Collenchyma cells have thickened cell walls, especially at the corners where they are in contact, providing mechanical support without hindering elongation. This tissue is often found beneath the epidermis in stems, petioles, and other parts undergoing active growth. The flexibility of collenchyma allows for bending without breaking, aiding in the plant’s ability to withstand mechanical stress. As the plant matures, collenchyma may be replaced by the more rigid sclerenchyma tissue for long-term support.
