What is the lifespan of an annual plant?

• A. Two years
• B. One year
• C. Three years
• D. Indefinite until conditions are poor

Answer: (B)

The lifespan of an annual plant is indeed one year. Annual plants complete their entire life cycle, from germination to flowering and seed production, within a single growing season. After they produce seeds, they typically die. This characteristic distinguishes them from biennial plants, which live for two years, and perennial plants, which can live for multiple years, often returning each season. Understanding the lifecycle of annual plants is essential in agriculture and gardening, as these plants are often chosen for their ability to produce quick, harvestable yields. Their short lifespan allows for multiple generations of growth within a single year, making them ideal for seasonal planting strategies. Annuals are commonly seen in crops like wheat and corn, which are planted, harvested, and replanted in successive seasons.
