Collenchyma: Collenchyma cells are polygonal in shape. Sclerenchyma consists of dead cells at maturity and thus why protoplast is absent. Parenchyma, collenchyama, and sclerenchyma are three types of simple, permanent tissues, collectively called ground tissue in plants. Sclerenchyma is a supportive or protective tissue in higher plants (vascular plants) composed of cells with walls thickened and often lignified. Structure of Parenchyma Cells Parenchyma cells are notable for their thin walls, and for being alive at … Parenchyma: Intercellular space is present between parenchyma cells. Sclerenchyma: Providing mechanical support, protection and transportation of water and nutrients are the major functions of sclerenchyma. They are a type of simple permanent tissue that also forms a part of the ground tissues along with parenchyma and collenchyma in plants.. Generally, they are also live cells that provide support and structure. Shoot-from shoot apical meristem . The term "sclerenchyma" is derived from the Greek σκληρός ("sklē-rós"), meaning "hard". collenchyma, also a living tissue, provides mechanical support to the growing parts of the plant such as young stem and petiole of a leaf. Parenchyma is a tissue composed of living cells, usually Parenchyma Cells . It is made up of living cells. Collenchyma and sclerenchyma tissues have … 2017.
