Detailed explanation-1: -Some roots, called adventitious roots, arise from an organ other than the root-usually a stem, sometimes a leaf. They are especially numerous on underground stems, such as rhizomes, corms, and tubers, and make it possible to vegetatively propagate many plants from stem or leaf cuttings.
Detailed explanation-2: -Adventitious roots can be found in grass, Monstera, and banyan trees. Grass and Monstera are monocots whereas, the banyan tree (Ficus) is a dicot.
Detailed explanation-3: -An example of adventitious roots in plants is Banyan whose scientific name is Ficus benghalensis. These are known as prop roots.
Detailed explanation-4: -Fibrous roots are also known as adventitious roots because the primary root that forms when a seedling germinates does not remain. Instead, roots grow out of the stem of the plant and are called adventitious. Fibrous roots are characteristic of monocots (Chapter 9), such as corn and grass (Figure 2.1. 2).
Detailed explanation-5: -The roots which develops from any part of the plant except the radical of an embryo or its derivatives are called an adventitious roots.
