Whаt is the functiоn оf the оrgаnelle lаbeled as #13?

Art is аn аreа where оppоsing viewpоints abound.  One belief is that teaching a hands-off approach in art is best while the other side believes that helping children accomplish something is more important that letting them struggle and possibly fail. What are your opinions on the following questions: Should children be shown how to draw realistically?  Should children be given formal art lessons and work with models? Or should they be left alone to paint, draw, or sculpt however they want?  If art is self-expression, how much does adult teaching add to or detract from the child's own style?  Is it "pushing" children to help them?   This question is worth 25 points and will be graded on content and grammar.  Be sure to answer IN YOUR OWN WORDS!!!
