What is a method of sexual propagation in plants?

Sexual propagation in plants involves the reproduction that occurs through the fusion of gametes, typically resulting in the formation of seeds. Seeding is a method where seeds, containing a combination of genetic material from both parent plants, are planted in soil to germinate and grow into new plants. This process is essential for the continuation of many plant species and is often preferred for its ability to produce genetically diverse offspring.

In contrast, methods such as cutting, layering, and grafting are forms of asexual propagation. These techniques allow for the reproduction of plants without the formation of seeds and, therefore, do not involve sexual reproduction. Cutting involves taking a part of a plant—like a stem or leaf—and encouraging it to root and grow into a new plant. Layering involves inducing roots to grow from a stem while it is still attached to the parent plant. Grafting is a method where tissues from one plant are joined with another, allowing them to grow together as a single plant. These asexual methods are useful for propagating specific varieties with desirable traits but do not produce seed or involve sexual reproduction.
