11. Answer is C.
They are located between epidermis and vascular cylinder.
12. Answer is B.
Dermal tissue system ( epidermis)is the outer protective layer of the plant body ( roots, stems leaves, fruits , flowers and seeds).
13. Answer is B.
It is false because the ground tissue system of the plant is called parenchyma.
14. Answer is D.
In plant anatomy seive tube elements are a specialised type of elongated cells In phloem tissue of the plants.
15. Answer is D.
Xylem is of two types cells like tracheids and vessel elements. Both of them have thick lignified secondary walls and are dead at maturity. They act like pipes to allow water and dissolved minerals flow through them.
16. Answer is B.
Lignins are particularly important in the formation of cell wall specially in wood and bark because they lend rigidity and do not rot easily.
