Which statement about cool-season grasses' life cycles is true?

• A. Most cool-season grasses have biennial life cycles
• B. Most cool-season grasses have annual life cycles
• C. Most cool-season grasses have perennial life cycles
• D. The material provides no information about life cycle duration

Answer: (B)

Cool-season grasses used in turf are perennial; they live for several growing seasons and come back year after year. They survive winter by going dormant or over-wintering, then green up again in spring and regrow from crowns, tillers, or rhizomes. Because the plant persists beyond a single season, its life cycle isn’t completed in one year. An annual pattern would mean the plant dies after one growing season, and a biennial pattern would span two years before dying, neither of which describes established cool-season turf. So the statement that most cool-season grasses have perennial life cycles is the accurate description.
