"After a plant has grown to maturity it will aim to produce an abundance of seed in order to create a new generation of plants. Annual plants complete this process then die within a year, biennials require 2 years to complete their life cycle and perennials can survive for many years.
Not only do seeds perpetuate the species into the future, more importantly they create a variety of individual seedlings. Some of these individuals will be more successful at surviving changes in the environment and as a result the species is able to adapt to new environments."
