what precisely does an inside architect do (vs simply architect)

i’m making use of for uni (beneath is the portfolio necessities) and that i dont fairly perceive what inside architects do, absolutely the architect does all of the partitions, the designer and different specialists do the remaining.

particularly with it asking for colored renders, if it was like structure why would that matter? absolutely that may be design as an alternative

that is my backup alternative, im usually a superb artist, so im a little bit confused and google isnt useful in any respect
