Which of the following describes the growth pattern of winter annuals?

The growth pattern of winter annuals is characterized by germination in the fall. These plants typically sprout during the cooler temperatures of late autumn, where they establish their root systems before the onset of winter. The cold period allows them to undergo necessary physiological changes, and when temperatures rise in the spring, winter annuals will accelerate their growth, flower, and set seed. This growth pattern is crucial because it enables them to take advantage of spring's favorable conditions for reproduction.

Other growth patterns, such as germination in the spring or continuous growth throughout the year, do not accurately describe winter annuals. Germination in the spring applies to other plant types, while growth all year long is not typical for winter annuals, which have a specific lifecycle that is completed by late spring or early summer.
