In legumes, it has been shown that "sleep" movements are correlated with
A) positive thigmotropisms.
B) rhythmic opening and closing of K+ channels in motor cell membranes.
C) senescence (the aging process in plants).
D) flowering and fruit development.

Question

Quizplus · Accepted Answer

Sleep movements in legumes are caused by rhythmic opening and closing of potassium (K+) channels in motor cell membranes. This allows for changes in turgor pressure and movement of plant parts. Thigmotropisms (movement in response to touch), senescence, flowering, and fruit development are not directly correlated with sleep movements.
