In the given diagram of the root apical meristem, what would be true for the structure labeled as number 1?

1. The cells in the region continually divide to produce cells of region 5
2. The cells in this region divide at much faster rate than the cells of region 2
3. The cells of this region are able to repopulate the borderline meristematic regions when they are injured
4. The cells of this region include the initials of region 3

Match the parts labeled as A, B and C in the diagram of stem apex with their derivatives in the plant body:

2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. Both I and II are false

The given diagram shows the central core of root in a certain plant. P is phloem and protoxylem elements and V is metaxylem. What is correct for structures indicated by arrows?

1. They show aerenchyma essential for aeration of root cells
2. They show cells in the roots that contain chloroplast
3. They show cells lack the characteristic radial and inner tangential wall thickening which is common to endodermal cells
4. They show cells that store resins and oils in the roots
