Identify the tissues based upon the following characters respectively: I) Large, colourless, empty cells along with leaf veins are used for absorption of water A) Axillary bud II) Cells much elongated, unbranched with pointed needle like apices and thick cell wall are dead at maturity B) Phloem fibre III) The cells are longitudinally arranged with perforated end walls C) Bulliform cells IV) Cells left behind from shoot apical meristem D) Sieve tube elements

I = C , II = B , III = D , IV = A

I = A , II = B , III = D , IV = C

I = B , II = C , III = D , IV = A

I = A , II = C , III = D , IV = B

Assertion ( A ) : The peripheral region of the secondary xylem is lighter in colour and is known as the sapwood (alburnum). Reason ( R ) : It is involved in the conduction of water and minerals from root to leaf. The correct answer is:

Both ( A ) and ( R ) are true. ( R ) is the correct explanation of ( A )
