Detailed explanation-1: -Like parenchyma cells, collenchyma is living at maturity. Collenchyma cells have thick primary walls composed of cellulose.
Detailed explanation-2: -Collenchyma-Are similar to parenchyma cells with thicker cell walls. They are meant to provide mechanical support to the plant structure in parts such as petiole of the leaf.
Detailed explanation-3: -The main characteristics of parenchyma are: They are living permanent tissues that have the ability to divide at maturity and help in the regeneration and healing of wounds. Parenchyma cells are the foundation of a plant as reproductive cells (spores, gametes) are parenchymatous in nature.
Detailed explanation-4: -Structure of Parenchyma Cells: They can also be oval, polygonal, elongated, or round. Such cells are packed tightly or may have limited intercellular space. They are built up of a thin cell wall that is mainly composed of cellulose, hemicellulose. Cells of the parenchyma tissue are joined by plasmodesmata.
