The meristematic tissue responsible for the cutting off vascular tissues (xylem and phloem) is called
1 Cork cambium
2 Vascular cambium
3 Lateral meristem
4 Endodermis
Explanation:
The meristematic layer that is responsible for cutting off vascular tissues - xylem and pholem - is called vascular cambium.

In young stem, the vascular cambium is
1 Depends on the plant
2 Bilayered
3 Single layer
4 Depends on the season
Explanation:
In the young stem vascular cambium is present in patches as a single layer between the xylem and phloem.

Secondary growth in plant
1 Means increase in girth
2 Results due to loss of differentiation
3 Results from lateral meristems
4 All of them
Explanation:
Secondary growth refers to increase in girth of plant due to the formation of secondary tissues by the two lateral meristems, i.e. vascular cambium and cork cambium.

The annual and spirally thickened conducting elements generally develop in the protoxylem when the root or stem is
1 Maturing
2 Elongating
3 Widening
4 Differentiating
Explanation:
Vessels or tracheae are made up of a row of cells, placed one above the other with the intervening walls absent or variously pored. The walls of vessels are lignified and hard but not very thick. The cell cavity or the lumen is wide, thickenings may be annular, spiral, scalariform etc.
