Hi Gazal, My name is Paul. I am an English-speaking native. I was looking at the small chart /table of phrasal verbs you posted. There is a mistake in the first example with regard to the meaning. To wake up does NOT mean to get up. They are NOT synonymous! (They do not mean the same thing!) To wake up means that you awake from a state of sleep to a state of alertness in which you are aware of what is happening around you. For example: When I woke up this morning, I heard the birds singing. To get up means to physically get out of (your) bed. I hope this helps you. 😀
