- Root hair, Xylem vessel, Soil particles, Cortex respectively.
- Xylem vessel, Soil particles, Root hair, Cortex respectively.
- Root hair, Xylem vessel, Cortex, Soil particles respectively.

- Adhesive force
- Capillarity
- Suction force
- The kind of force between the same kind of liquid molecules is:
- Capillary force
- Transpirational pull
- Adhesive force
- Cohesive force
- Sometimes exudation of water occurs from the margin of the leaves in the early morning or night. It is termed as:
