Quizplus · Accepted Answer

Vernalization is the requirement of exposure to cold temperatures in order for a plant process to occur, such as the induction of flowering or germination. The biological clock refers to an internal timing mechanism within an organism, while photoperiodism refers to the response of an organism to the duration of daylight. Biennial and perennial life cycles refer to the number of years it takes for a plant to complete its life cycle.
