Why do leaves on an pink silk tree bow downwards?

Leaves on a pink silk tree, like those of many other plants, may bow downwards due to a phenomenon known as phototropism, where they orient themselves to maximize light absorption for photosynthesis. Additionally, gravity can also influence their downward growth through a process called gravitropism. Environmental factors such as water availability and the tree's overall health might also affect leaf orientation. This bowing can help reduce water loss and protect the leaves from excessive sunlight or wind.
