Identify the simple permanent plant tissue with the following descriptions and also mention their location in the plant body:
$(a)$ Cells have irregular wall thickenings.
$(b)$ Tissues with large intercellular spaces and cells having large air cavity.
$(c)$ Cells are long,narrow,and dead in nature.

(N/A) Collenchyma: These cells have irregular thickenings of pectin and cellulose at the corners. Location: Found in the leaf stalks below the epidermis.
$(b)$ Aerenchyma: $A$ type of parenchyma tissue with large intercellular spaces and air cavities to provide buoyancy. Location: Found in the stems and leaves of aquatic plants.
$(c)$ Sclerenchyma: These cells are long,narrow,and dead at maturity due to lignin deposition. Location: Found in the hard parts of the plant such as seed coats,fruit walls,and vascular bundles.
