Difference Between Collenchyma and Chlorenchyma | Collenchyma vs Chlorenchyma


The key difference between collenchyma and chlorenchyma is that collenchyma is a type of ground tissue that provides mechanical and structural support to a plant while chlorenchyma is a modified parenchyma tissue that contains chloroplasts and is photosynthetic.

There are three types of ground tissue as parenchyma, collenchyma, and sclerenchyma. They are neither dermal nor vascular. Parenchyma cells are typical plant cells with thin primary cell walls. They remain alive even at maturity. Parenchyma cells act as the filler tissue in the soft parts of the plants. On the other hand, collenchyma cells also have primary cell walls, but they possess secondary thickenings in some areas of the cell wall. Hence, they provide mechanical support as well as structural support to the plant. Moreover, sclerenchyma cells have heavily thickened secondary cell walls, but these cells die at maturity. They don’t contain nucleus and cytoplasm at this stage. Also, they are the prime cells that provide structural support to the plant. Thus, chlorenchyma is a special type of parenchyma tissue which is photosynthetic.

What is Collenchyma?

Collenchyma is one of the three types of ground tissues present in plants. Collenchyma cells have unevenly thickened primary cell walls. The cell wall is made up of pectin and hemicellulose. These cells are elongated or angular in shape in transverse sections. These cells are living cells even at maturity though they have cell wall thickenings. There is only a small space/no space between collenchyma cells.
