Final answer:
Plants generally begin their growth cycles again during the spring season, as the temperatures become warm enough to support their growth and development.
Step-by-step explanation:
These plants begin their growth cycles again during the spring season. The annual temperature variation dictates specific growing seasons for plants, allowing growth when conditions are warm enough, typically in the spring, summer, and fall.
Most annual plants, such as wheat in northern regions, start their growth cycle in spring. Perennials may also begin new growth in spring after lying dormant in the colder months. The critical elements that contribute to the growth cycles of plants are warmer temperatures and the availability of water and nutrients. These conditions most commonly occur in the spring after winter's cold has passed and when daylight begins to increase.
Plants like winter annuals, germinate in fall, overwinter and then resume growth to flower in spring. While for perennials and biennials, such as carrots and magnolias, the spring marks either a continuation of their lifecycle or the start of a reproductive phase.
