WebCircadian Responses Keeping time with biological clocks. 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. WebCircadian Clock. The circadian clock has an internally driven 24-hour rhythm that tends to run longer than 24 hours but resets every day by the sun’s light/dark cycle. Taking …
