Detailed explanation-1: -Parenchyma cells are typically oval or round in shape, while collenchyma cells usually look like elongated rectangles. And as you can see, sclerenchyma cells vary widely in their shape and size. You might notice that parenchyma cells have the thinnest cell walls of all three tissue types.
Detailed explanation-2: -Parenchymatous tissues have intercellular spaces is a wrong statement. Parenchyma act as a packing tissue in plants hence they do not have intercellular spaces.
Detailed explanation-3: -Parenchyma consists of relatively large, thin-walled cells. The cells are arranged loosely, that is, there are intercellular spaces among them. The protoplasts of these cells contain chloroplasts.
Detailed explanation-4: -In aquatic plants, large air cavities are present in parenchyma to give buoyancy to the plants to help them float.
