Structure 6 is the Rough Endoplasmic Reticulum ( RER) while structure 7 is the Golgi apparatus.

Explanation:

The RER has ribosomes aligning its outer membrane (reason why it's referred to as called rough ER). The ribosomes manufacture polypeptide chains that enter the lumen of the RER. The polypeptide chains are properly folded using chaperones in the lumen of the RER and undergo post-translation modifications, These proteins then undergo Quality Control checks and the proper ones are allowed to proceed to the Golgi apparatus.

Proteins from the RER reach the Golgi apparatus through vesicles that bud off of the <em>trans</em> side of the RER then fuse with the <em>cis </em>side of the Golgi apparatus. The Golgi perform a few more modifications to the proteins including tagging them for delivery , then packages them. Vesicles carrying the proteins bud off of the <em>trans</em> side of the Golgi and get transported to their destination inside or outside the cell.
