The roots which develop from any part of the plant other than the radical are known by which of the following?

Adventitious roots are roots that develop from a part of the plant other than the radicle or the embryonic root, which is formed during germination. They can arise from various tissues, such as stems, leaves, and even flowers, and often appear as lateral roots or clusters of roots.

Adventitious roots play a crucial role in plant survival as they help to anchor the plant firmly in the soil and provide additional support to the stem, leaves, and other above-ground plant parts. Additionally, they can absorb water and nutrients from the soil, supplementing the function of the primary root system.
