Deciduous plants lose their leaves each year in response to changes in the day length.The biorhythm exemplified in the given statement is
Correct answer: B. Circannual rhythm
- A. Circadian rhythm
- B. Circannual rhythm
- C. Circatidal rhythm
- D. Circalunar rhythm
Explanation
The correct answer is Option B: circannual rhythm. This is because deciduous plants lose their leaves once a year, which aligns with the annual cycle characteristic of circannual rhythms.Option A, circadian rhythm, is incorrect because it involves daily cycles. Option C, circatidal rhythm, is incorrect because it involves tidal patterns, typically occurring multiple times a day. Option D, circalunar rhythm, is incorrect because it involves monthly cycles related to the lunar phases, not annual changes.

About Regeneration and Ageing
Regeneration is the replacement of lost or damaged cells, tissues or body parts, ranging from ordinary tissue repair to regrowth in organisms such as planarians. Ageing covers progressive cellular and physiological decline, including reduced repair, senescence, genetic and environmental influences, and the difference between normal ageing and disease.
