Plants utilize seeds for reproduction primarily as a means to disperse offspring. Seeds are the vehicle for transferring genetic material from one generation to the next, and their formation allows for the propagation of plant species in various environments. The dispersal mechanisms can include wind, water, or animals, which help the seeds to spread away from the parent plant. This dispersal increases the likelihood of survival for the offspring by reducing competition for resources with the parent and promoting genetic diversity by allowing plants to colonize new areas.

In this context, while seeds do serve to collect water to an extent, store energy in the form of nutrients, and can play a role in disease resistance, these functions are secondary to their primary role in the life cycle of flowering plants, which is reproduction and the strategic spread of the species.
