Is the any point to having both Chrome and Google search on my phone? Between the two programs they take up a lot of space on my phone

 

This may be a stupid question, but this is a metro PCs phone. It came with a load of Google stuff on it and Google search. Is that the same as plain old Google. Chrome was preloaded also. It uses 133mb while Google search only uses 57mb. With such limited space, I'd like to eliminate what I can.
