can you please let me know what is the difference between the function and store procedure and why we need to pass parameters in them

You might want to think of a function as something that "takes an input, does something with it, and then gives something back"; where a stored procedure is just any collection of statements that can be executed as a group.

I have a coworker who is very knowledgeable about stored procedures and this course is covering even the "gotchas" that he mentioned. Start here if you want to learn them, at least until Treehouse adds some courses: https://www.pluralsight.com/courses/sql-server-database-programming-stored-procedures
