What defines annual plants?

What defines annual plants?

• A. Complete life cycle in less than 12 months
• B. Live more than 2 years
• C. Produce only vegetative growth
• D. Woody stems throughout life

Answer: (A)

Annual plants complete their entire life cycle in one growing season: they germinate, grow, flower, produce seeds, and die within a single year. This brief life span means the next generation comes from the seeds produced that season. Perennials live for several years and often come back year after year; biennials take two growing seasons to complete their cycle; and woody-stemmed plants like trees and shrubs persist for many years. The defining feature here is finishing the life cycle in less than 12 months, so that option best describes annual plants.
