Plants that live for one year or less are classified as annuals. These plants complete their life cycle — germination, growth, flowering, seed production, and death — within a single growing season. This rapid cycle allows them to take advantage of favorable conditions quickly, often producing seeds before the onset of unfavorable conditions such as winter.

Annuals can be further divided into two categories: summer and winter annuals, depending on the season in which they germinate. Summer annuals grow in the warmer months, while winter annuals germinate in the fall, survive the winter as seeds or small plants, and complete their life cycle in spring.

On the other hand, biennials take two years to complete their life cycle, while perennials live for multiple years, often regrowing each season from their root systems. The term "decennial" is not commonly used in plant classification and typically refers to a ten-year period rather than a life cycle of a plant. Thus, the correct classification for plants living one year or less is indeed annual.
