What is vegetative propagation? Give one example of vegetative propagation and state whether it involves a stem, a root, a leaf or a bud - Leaving Cert Biology - Question b - 2005

One example of vegetative propagation is the propagation of a potato plant through tubers. This involves the root structure, as the tuber is an enlarged storage organ that allows new plants to grow from it.

Vegetative propagation differs from reproduction by seed in that it does not involve sexual reproduction. In vegetative propagation, new plants are produced from the vegetative parts of the parent plant, ensuring that the offspring are genetically identical to the parent. In contrast, seed reproduction involves the fusion of gametes from two parent plants, resulting in genetic variation among offspring.

Two examples of artificial propagation are:

1. Grafting: This involves joining the tissues of two plants so they grow together as one.
2. Cuttings: This method involves taking a part of a plant, such as a stem or leaf, and encouraging it to grow roots in a suitable medium.

One advantage of artificial propagation is that it allows for rapid production of new plants that are genetically identical to the parent, ensuring desired traits are conserved. A disadvantage is that it can lead to reduced genetic diversity, making plants more susceptible to diseases and environmental changes.
