Lab Practical. Gravitropism: The role for roots

This experiment using agar plates and white mustard seeds allows students to visualise the development of roots, their root hair cells, and observe the zones of elongation and differentiation. They will then use a graticule to measure their length. Students can then extend their investigations to observe the effect of an obstruction in the path of the roots, visualise the xylem in roots using food dye, and observe gravitropism in the roots.
