How long do annual plants typically live?

Annual plants typically live for one year or less, which is why the choice indicating this duration is correct. These plants complete their entire life cycle—from germination to production of seeds—within a single growing season. After they have produced seeds, they die off, and the seeds may remain dormant until the next ideal conditions for germination arise.

In contrast, other types of plants, such as perennials, can live for multiple years and regrow every spring, while biennials take two years to complete their life cycle. The choice indicating 'more than two years' or 'indefinitely' does not accurately describe the lifespan of annual plants, as they do not persist beyond a single growing season. Therefore, understanding the growth patterns and life cycles of annual plants is crucial for managing them effectively in agriculture and gardening.
