Phloem

Part one of an in-depth series. Getting your hands dirty in the garden or diving into botany can be a much richer experience when you understand the various parts of a plant and their functions.

Roots are almost always underground, but these hidden systems are responsible for a range of functions from securing the plant in the soil to absorbing water and nutrients. You can think of the root system as the foundation of a building: it's what keeps the plant stable, nourished, and capable of growth throughout its life cycle.
