In dicot stem, the secondary growth takes place by
1 primary cambium
2 secondary cambium
3 development of cambium in stele region
4 development of cambium in stele and in the cortical region.
Explanation:
(d)At the initial stage of secondary growth, cambium forms a ring like structure known as cambium ring. This ring is present in stelar and cortical region both.

Conduction of sap in plants occur through
1 heartwood
2 sapwood
3 xylem
4 all of these
Explanation:
(b)Cells of sapwood are alive, and because of abundant pore spaces, movement of sap takes place through these tissues.

“Sapwood” is otherwise called
1 duramen

The function of cork cambium (phellogen) is to produce
1 cork and secondary cortex
2 secondary xylem and secondary phloem
3 cork
4 secondary cortex and phloem
Explanation:
(a)Cork cambium (phellogen)develops from outer layer of cortex. It produces secondary cortex (phelloderm)on inner side and cork (phellem)on outer side.
