Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls). The key difference between collenchyma and sclerenchyma is that collenchyma is a type of live plant cell that has irregularly thickened primary cell walls while sclerenchyma is a type of dead plant cell that has heavily thickened secondary walls.. The cells of this tissue are living, elongated and irregularly thickened at the corner. Aim: To observe and draw transverse sections of parenchyma, collenchyma, sclerenchyma, xylem, phloem and epidermal cells using a light microscope.

Difference Between Parenchyma Collenchyma and Sclerenchyma. Log in. The major function of sclerenchyma is support. Collenchyma provide mechanical strength to the plant particularly newly generated. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells. In collenchymas, intercellular spaces are generally absent. Sclerenchyma cells have very thick cell walls reinforced with the polyphenol polymer lignin. Add your answer and earn points. Ø They provide mechanical support mainly in the primary plant parts such as young stem, roots and leaves. 3.2 I-III) (i) Parenchyma: Parenchyma is the most common tissue which is morphologically and physiologically simple and unspecialized.
