  Seeds are actually one of the most nutritious parts of the plants and can be found in grocery stores or farmers markets. Normally, these parts of the plants are used exclusively for reproduction, with plants dispersing seeds on an annual basis to begin the next generation. The majority of edible varieties are composed of cereals, but others include beans and nuts.
