During fertilization in flowers, where is the complete blueprint found?

The complete blueprint for the plant is found in the seeds, which contain the embryo and a supply of nutrients that sustain it during germination. This blueprint is essentially the genetic information necessary for the development of a new plant, encoded in the form of DNA. The seeds are the result of fertilization, where the pollen fertilizes the ovule, leading to the formation of the zygote and ultimately, the seed.

Roots, stems, and leaves play vital roles in the growth and sustenance of the plant but do not contain the genetic information needed to form a new organism. Roots primarily absorb water and nutrients, stems serve as the support structure and transport system for nutrients and water, and leaves are involved in photosynthesis. While all parts of the plant contribute to its overall function and survival, the genetic blueprint essential for the next generation is concentrated in the seeds.
