All the components given constitute the ultrastructure of the nucleolus. 
1. Granular zone occupies the peripheral region of the nucleolus, which is surrounded by the associated chromatin.
2. The fibrillar zone contains fibrils (thread-like fibres) that contains ribonucleoprotein.
3. The amorphous component of the nucleolus begin to disappear during the first stage or prophase stage, but it reappears in the daughter cells. Otherwise called as Pars amorpha
