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
