Why do some aircraft have wings that tend to bend up?

Question

I take regular visits to the Boeing website, and when I look at some pictures, the wings tend to edge/point up. Why is this?

Are you asking about that bent bit at the end? (Winglets - see this question for a picture) — Dan Pichelman, Oct 26 '17 at 17:43
@TomMcW: Or it could be the upward flexing of the wings while in flight? Which has an answer here: https://aviation.stackexchange.com/questions/838/what-are-the-effects-of-the-boeing-787s-very-flexible-wings — jamesqf, Oct 26 '17 at 19:10

All wings do flex, but in some modern airliners, the wings are built, fully or in part, with modern composites, that may deform within a larger elastic interval than metals...
