Marigolds are annuals, so they complete their life cycle in one season. The seed is the embryo. It develops roots and sends up vegetative growth (seed leaf) called cotyledon. It continues to grow and photosynthesize, eventually resulting in a flower. Marigolds need to be pollinated to reproduce seed. The plants die once new seeds mature.
