When exposed to extreme weather conditions, some biennial plants will have a shorter life cycle. For example, a biennial plant that is exposed to extreme cold may have a life cycle of only 3 months instead of 2 years. This common occurrence has led some people to consider a typical biennial plant as an annual plant in some locations.
The first season of biennials is marked by the growth of a small rosette of leaves near the soil as well as its stem and roots. It stops growing at the onset of the cold months. During its second year a biennial plant will grow a longer stem and start sprouting flowers that develops into seed-bearing fruits before dying off.
Biennial plants that are cultivated for their edible roots or leaves are treated as annuals and are harvested each season. Those that are cultivated for their flowers, fruits or seeds needs to be grown for their full life cycles.Learn more about Biology

Biology plays an important role in the understanding of complex forms of life involving humans, animals and plants. Understanding these intricate details of life helps humans understand how to care for themselves, animals and plants in the proper manner. Biology helps individuals understand the interaction between humanity and the world. It also develops interests in the lives of living organisms in an effort to preserve them.Full Answer >
