Question

MEDAL AND FAN..PLEASE HELP
List two circadian responses that plants undergo at night.

Answer 1

Plants, like other living things, have biological clocks that allow them to respond to changes in time. Among the more obvious clock responses are "sleep movements" such as the closing of flowers and changes in leaf position that many plants display at night. The growth rate of most plants also differs according to time of the day in a clock-dependent fashion. In addition, changes in expression of genes and many biochemical activities are under control of the biological clock. The circadian clock that controls these and other time-dependent responses requires environmental cues to stay synchronized with the 24 hours of the day. Light and temperature are two of the most important environmental stimuli since they usually change between night and day.
