A plant that lives many years is called a __________.

1. annual

2. biennial

3. perennial

4. deciduous

The correct answer is: perennial

A plant that lives many years is referred to as a perennial. Perennials are characterized by their ability to survive through multiple growing seasons, often returning year after year. They typically go through a period of growth, flowering, and dormancy, but will regrow from their root system or crown when conditions are suitable, such as in spring. In contrast, annual plants complete their life cycle within a single growing season, germinating, flowering, and dying all in the same year. Biennials live for two years, typically growing in the first year and flowering in the second before they die. Deciduous refers to plants that shed their leaves seasonally, but this term does not specifically indicate the lifespan of the plant. Understanding these definitions is crucial for effective crop management and horticulture practices, as it aids in selecting the right type of plants based on growth cycle and longevity.
