Which type of plant is most likely to reseed every year and complete its life cycle in one season?

The chosen answer is accurate because an annual plant is specifically defined by its life cycle, which is completed within a single growing season. Annuals typically germinate, bloom, produce seeds, and die all within the same year. This growth cycle allows them to reseed themselves yearly as the seeds they produce can sprout the following growing season.

In contrast, perennial plants live for multiple years and may not complete their life cycle in one season, whereas biennials require two years to complete their life cycle, flowering in the second year after establishing in the first. Winter annuals are a subset of annuals that specifically germinate in the fall, survive winter, and complete their life cycle in the spring. However, since the question encompasses a broad category, the most accurate choice remains annual, recognizing its broad application across typical growing seasons.
