The root is a single celled embryo that grows into a mature plant.
The root has a cortex, a stem, and roots below the soil.
The root has a system of roots that spread and develop in different directions.
There are two types of root systems: axial and fasciculated.
The root system of an axial system is well developed with lateral roots that are little developed.
The root system of a fasciculated system lacks a dominant root.
Roots can be aerial, ground, or aquatic.
Roots can have associations with microorganisms, nodules, and root hairs.
Aquatic roots can have associations with aquatic bacteria that help with nitrogen fixation.
Roots can be leggy or have a negative geotropism.
Plants can have different root systems for different functions.
