Study Notes
- 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.
