Answer Details
An example of an organ of perennation in plants is a rhizome. Perennation refers to the survival of a plant from one growing season to another. Rhizomes are specialized underground stems that grow horizontally, producing roots and shoots at intervals. They serve as a food storage organ and also help plants survive adverse environmental conditions.
During unfavorable conditions such as drought or extreme temperatures, the above-ground parts of the plant may die back, but the rhizome can remain dormant until conditions improve. When the environment becomes favorable again, the rhizome can sprout new shoots and leaves, allowing the plant to continue growing.
Seeds can also serve as organs of perennation, allowing plants to survive through unfavorable conditions, but they are not considered examples of organs of perennation since they are not a part of the plant itself. Petals and calyx of flowers are not organs of perennation because they are involved in reproduction and not survival from one growing season to another.
