The diagrams illustrate transverse sections of a dicotyledonous root, stem and leaf. The vascular tissues are marked with the numbers 1-6. The cut ends of root pieces, stem pieces and leaf stalks are put into water that contains a red dye. After several hours, the coloured water has moved through some of the vascular tissues. Which vascular tissues are shown in red?
- Aroot 1, stem 3, leaf 6
- Broot 1, stem 4, leaf 5
- Croot 2, stem 4, leaf 6
- Droot 2, stem 3, leaf 5
