Sieve tube
It is present in the phloem tissue. It's function is the transportation of synthesised food through out the plant. 
Interfascicular Cambium
It's function is to bring about secondary growth in the dicot stem and root. It is a kind of secondary meristematic tissue present in between two vascular bundles.
Collenchyma
It's function is to provide mechanical support to young growing herbaceous stem. It's cells have angular thickening at corners.
Aerenchyma
It provides buyoncy to the hydrophytic plants. It is a specialised parenchyma having large air species.
