I have done projects using Arduino IDE.I have seen that many projects can be easily implemented using the IDE.Then, why should one learn register level programing? How important is it?
Why should one learn register level programing for embedded systems, when options like Arduino IDE ,etc are available?

Learning register level programming will help you learning how to read a datasheet, and also understanding how stuff works. It will give you more flexibility after you get the hang of it, plus you can optimize your code and write your own libraries.
By knowing how to read a datasheet it will be easier for you to develop device drivers and process algorithms.
What would you do if you cannot find an Arduino library for a certain sensor? If you were using register level programming, you could easily write your driver, by already knowing how to interpret the technical files ;).
Try it out, you will forget Arduino in the first weeks!

Can you do EVERYTHING with the Arduino library? If your project would need tight timing (for example to control a huge industrial apparatus), at the level of microsecond fractions, would Arduino still be a good choice? How about medical devices? How about performance - would you be able to design a BLDC controller using Vector Control in Arduino? How about battery life - would you be able to design a device that would run with a single CR2032 cell for a few years using Arduino? How about doing a network router? Does Arduino support threads?
Your question is like one of these:
To be honest, personally (I write firmware for embedded devices),I see Arduino as a toy, nothing more.
