Nucleolus where ribosomes (and some signal recognizing molecules) are created

Cytoeskeleton mesh of microtubules and actine filaments along which molecular motors walk

Centrosome organizes microtubules. It's where they originate. I think it's like the seed for their self-assembly

Golgi apparatus packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination

Endoplsamatic reticulum. Proteins self-assemble inside them. More stuff

This is how proteins are pushed inside the endoplasmatic reticuli while the ribosome assembles them:

Cytoskeleton
