Define the purpose for writing shell scripts as a superuser?
I presume you mean writing shell scripts that operate under the super user account - scripts are written for any reason to help automate tasks and make them much less error prone than issuing commands as a user. Running as the superuser merely means that the commands in the shell script require superuser priviledge to execute.
When might it be necessary or advisable to write a shell script instead of a shell function?
A shell function will do nothing unless it is explicitly called by other code, typically in a shell script. A shell script is a runnable, executable process, which can call other shell scripts and/or functions. The question might be worded backwards - it is necessary to write shell functions for shell scripts when certain logical functionality is required to be performed multiple times. Consider a shell function equivalent to a program subroutine - they operate the same way.
What do you call the programs that sorround the kernel of the operating system?

What problems will you encounter if you delete the PATH variable?
PATH is a system variable used by the "shell" to determine where to find programs that are executable. This variable exists in similar forms on both Windows and Linux operating systems (and other related or similarly-designed systems). Removing this variable will not specifically stop the graphical user interface for the system from working correctly, but it will interfere with the execution of "shell scripts", users that attempt to use the command line interface (terminal) and programs that depend on the shell to execute child processes.
