Which plant dies after completing one year of its life?

Question

Which is the plant, a member of the Amaranth family, native to the Andes in South America, the seeds of which are a staple food crop in parts of South America and are now grown around the world?

Answer 1

These type of plants are called annual plants which dies after plants produce mature seeds, having exhausted themselves from sprouting, growing foliage and flowers, and finally producing viable seed in just one growing season. The mother plant dies, but she may have left hundreds, or even thousands, of seeds to carry on her legacy.

For annual plants, one generation per year is the norm, so they have a life cycle of one growing season.

Example: beans, cosmos, broccoli and many garden plants...
