Final answer:
Annual plants typically have a short lifespan, completing their lifecycle within one year, as opposed to biennials or perennials which take more time. Considering the provided options for the specific question, the answer is: 1) Short lifespan.
Step-by-step explanation:
Annual plants typically have a short lifespan, completing their lifecycle within one season. It means that these plants grow, produce seeds, and die within a single year. A popular example of an annual plant is the Arabidopsis, also known as mouse-ear cress. In contrast, biennials, such as carrots, take two seasons to complete their lifecycle, with their first season usually focused on vegetative growth and the second on reproduction.
Unlike annuals and biennials, perennials like the magnolia plant can live for more than two years, going through repeated cycles of growth and reproduction over their lifespan.
