• Numerous small roots that spread out in all directions

• A combination of large and small roots that spread out in all directions

What are adventitious roots?

• Roots that develop from the flowers of the plant.

• Roots that develop from any part of the plant other than the radicle or the root axis.

• Roots that develop from the leaves of the plant.
