The roots are modified to have root hairs and branch indiscriminately with cells that take in water and nutrients, while the stems are modified to move water and nutrients to and from the leaves and flowers.

How do roots grow underground?

As the stem and leaves grow on the surface, additional roots expand underground. Lateral roots branch off the tap root. These form close to the surface of the soil where most of the water and nutrients are found. Thus a wide matt of roots radiates out from the trunk, parallel with the soil, creating a “root plate”.
