Explanation:

• Parenchyma cells are relatively unspecified and thin-walled. It is a functional part of an organ and in contrast to the stroma, it refers to the structural tissue of organs which are the connective tissues.
• Parenchyma tissue is composed of thin-walled cells and makes up the photosynthetic tissue in leaves, the pulp of fruits, and the endosperm of many seeds.
• Plants have evolved by using special structures within their cells to harness energy directly from sunlight.
• Parenchyma cells in plants provide mechanical support when they become lignified and thickly walled.
• Sclerenchyma cells have thickened lignified walls, which make them strong and waterproof. They are commonly classified into support types and conducting forms.
