Expert Answer:

Parenchyma provides support to plants and also stores food. It is a basic packing tissue in plants. Parenchyma of stems and roots store water and nutrients. Sometimes it contains chlorophyll and performs photosynthesis ( called chlorenchyma) . In aquatic plants, parenchyma ( called aerenchyma) shows large air spaces to give buoyancy to plant.

Collenchyma allows easy bending in various parts of the plant without breaking. It also provides mechanical support to the plants.

Sclerenchyma provides strength and protection to the plants.
