Cells of ________ tissue are living, show angular wall thickenings and provide mechanical support.

Step-by-step solution

Collenchyma, part of the ground tissue, is a simple living tissue found in plants. Collenchyma layer is generally found below epidermis of the plant. They are either found in a patch manner or even distributed throughout. The cell wall of collenchyma tissue cells is thickened at corner due to higher deposition of cellulose, pectin and hemicellulose. The cells are generally spherical or polygonal in shape. This tissue provides mechanical support to the young stem and leaf. Parenchyma is a type of simple permanent ti
