Ø Cells do not have protoplast when they completely developed. What is the function of collenchyma cells? The functional difference between collenchyma and sclerenchyma is that the collenchyma tissue provides mechanical support and elasticity to plants while sclerenchyma tissue provides mechanical support and rigidity to plants. Collenchyma is found below the epidermis in petiole, leaves and stem in dicots and provides mechanical strength to the plant. The cells are arranged loosely, that is, there are intercellular spaces among them. The tissue is made up of living cells that have cellulose, hemicellulose and pectin thickenings at the corners. Collenchyma is a tissue composed of elongated cells with irregular thick cell walls that provide support and structure. The cell walls consist primarily of either cellulose or cellulose and pectin. Their size, shape, and structure vary greatly. Functions. consists of relatively large, thin-walled cells.. The main difference between collenchyma and chlorenchyma is their structure and the occurrence. Physics. Major pit fields can be illustrious in the walls. Log in. Reference: 1. The primary collenchyma function is providing support for the growth of stems and other parts of dicot plants. Join now. Collenchyma tissue performs the following tasks: Collenchyma cell induces rigorousness to the rising parts like stems, leaves etc. Write the location and function of collenchyma tissue. Function:- (1) Collenchyma is a mechanical tissue in young dicotyledonous stems and provides mechanical support and elasticity. The major function of sclerenchyma is support. Sclerenchyma is a dead cell that has thick secondary cell walls found in the nongrowing regions of the plant body, such as bark and stems. Class 12 Class 11 Class 10 Class 9 Class 8 Class 7 Class 6.
