| $(3)$ Cells are usually loosely packed with large intercellular spaces. | $(3)$ No intercellular spaces are found between the cells. |
| $(4)$ Stores nutrients and water in stems and roots. | $(4)$ Provides mechanical strength to plant parts. |
| $(5)$ Some cells contain chlorophyll (chlorenchyma) and perform photosynthesis. Others have large air cavities (aerenchyma) providing buoyancy to aquatic plants. | $(5)$ Cells are long and narrow,making the plant hard and stiff. Found in stems,around vascular bundles,in leaf veins,and the hard covering of seeds and nuts. |
