Do you mean why these three phrases all containing a"起来” while they are of different meanings?
“起来” can be used as a verb,but sometimes you can also use it as a directional verb,which just follows a verb.
To be specific,it can be divided into three aspects,
1.[stand up]
你站起来 You stand up.
2.[get up]∶起床
我起来了=我起床了 I wake up
3.follow a verb
拿起来书=pick up the book 听起来=sound 闻起来=smell 看起来=seem
You can also regard it as a symbol of showing a thing has done or one has achieved his goal
Hope this helps/
