Dear student,
The permanent tissue is located at different regions of the plants. The parenchyma tissue is found in the epidermis, cortex, pericycle and the pith region of the plant. It is also found in the leaves, fruits, and flowers to store the food.
The collenchyma tissue is generally present below the epidermis region of the plant. They are found near to the growing tissue like vascular cambium. It is also present in the young stems and in the veins of the leaf.
The sclereids of sclerenchyma are found in the gritty texture of the pear and in the center of the apple along with the shells of many seeds and the nuts. The fibers of the sclerenchyma are found in the stem, roots and also in the vascular bundles of the leaf.
