Write the precise function of:
$(a)$ Sieve tube
$(b)$ Interfascicular cambium
$(c)$ Collenchyma
$(d)$ Aerenchyma

(N/A) Sieve tube: It is a component of the phloem tissue. Its primary function is the translocation of synthesized food (sugars) from source to sink throughout the plant body.
$(b)$ Interfascicular cambium: It is a type of secondary meristematic tissue that develops from medullary ray cells located between vascular bundles. Its function is to facilitate secondary growth in dicot stems and roots by producing secondary xylem and secondary phloem.
$(c)$ Collenchyma: It provides mechanical support to the growing parts of the plant,such as young stems and petioles of leaves. It allows for flexibility and tensile strength due to the uneven thickening of cell walls at the corners.
$(d)$ Aerenchyma: It is a specialized type of parenchyma tissue containing large air cavities. Its primary function is to provide buoyancy to aquatic plants,allowing them to float,and to facilitate gas exchange in submerged conditions.
