Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant.

Difference between parenchyma, collenchyma and sclerenchyma
Parenchyma Collenchyma Sclerenchyma
1. Primary cell wall is present. 1. Primary cell wall is present. 1. Secondary cell wall is present.
2. Parenchyma cells have thin cellulosic/hemicellulosic cell wall and normally do not show secondary wall thickening. 2. Collenchyma tissue has thick non-lignified walls with irregular cellulose thickening that provide mechanical support and tensile strength to the growing organs. 2. Sclerenchymatous tissue has uniformly thick lignified cell walls that provide mechanical support
