kollenkudokset
Kollenkudokset are a type of plant tissue that provides mechanical support and allows for growth. They are composed of living cells that are often elongated and may have thickened primary cell walls. Unlike sclerenchyma, which has rigid, lignified secondary cell walls, collenchyma cells typically remain extensible, allowing the plant to grow. This extensibility is often attributed to the uneven thickening of the cell walls, particularly at the corners.
Collenchyma tissue is commonly found in the growing stems, petioles, and along the veins of leaves of
The cells of collenchyma are generally characterized by their living protoplasts and the presence of pits
