Answer:
It is caused by phototropism. During the day, when light shines, the plant will grow towards the light. This causes the effect that parts of the plant in shade grow harder than parts in light, and hence they bend towards the light. During night this effect stops and therefore the leaves will droop.
Answer:
Yes this is normal behavior for many plants. It is caused by phototropism. During the day, when light shines, the plant will grow towards the light. This is caused by auxins, which are phytohormones. The most common method used by plants is that these auxins stimulate growth, but are degraded by light. This causes the effect that parts of the plant in shade grow harder than parts in light, and hence they bend towards the light. During night this effect stops and therefore the leaves will droop
